Susan went to dinner at San Felipe and ordered the ACP for $10.99. If she paid 8% tax, what was her total cost?
Please help!
Answer:
11.88 $ (approximately)
Step-by-step explanation:
10.99 is approximately 11
So
100$ …8$
1$ .… 8/100 $
11$… 8/100×11 $

0.88 $
So she total has to pay
11 + 0.88 $
11.88 $ (approximately)
A website rents new-release movies for $3 and older movies for $2. The revenue, r, of the website can be represented by the equation r = 3n + 2m, where n is the number of new-release movies rented and m is the number of older movies rented. Last month, the revenue was $6,840 and 1740 new release movies were rented Enter the number of older movies that were rented by solving for m.
m =
Answer:

Step-by-step explanation:
[tex]r=3n+2m[/tex]
Where
[tex]r=6840\\n=1740\\m=?[/tex]
[tex]6840=3(1740)+2m\\6840=5220+2m\\6840-5220=5220+2m-5220\\1620=2m\\\frac{1620}{2} =\frac{2m}{2} \\m=810[/tex]

Answer:
D. -3z+2
Step-by-step explanation:
Steps:
Remove parentheses: (a) = a
= 5z+9-(8z+7)
....
Simplify
5z+9-8z-7: -3z+2
Answer:
-3z +2
Step-by-step explanation:
A expression in terms of z is given to us and we need to simplify out the given expression . The give an expression to us is ,
[tex]\implies (5z + 9 ) - ( 8z + 7 )[/tex]
Recall that , + × - = - . We have ,
[tex]\implies 5z + 9 - 8z - 7 [/tex]
Combining the like terms and simplifying ,
[tex]\implies 5z - 8z - 7 +9 \\\\\implies \underline{\underline{ -3z +2 }}[/tex]
Hence the last option is correct .

Price of Rope
3 The amount a hardware store pays for buying nylon rope
is represented by the equation y = 0.12%, where y is the
price it pays for x feet of rope. The amount the hardware
store charges when selling the rope is represented by
the graph
The profit the store makes on the rope can be found by
subtracting the amount it charges for the rope from the
price it pays for the rope. If the store sells 80 feet of rope,
how much profit does it make on that rope?

Explanation:
Use the remote interior angle theorem. This says to add the interior angles shown, and you'll get the exterior angle that is not adjacent to those interior angles.
68+65 = 133
So angle B is 133 degrees
------------------
A longer alternative is to let C be the missing interior angle of the triangle. Then we can find that
68+65+C = 180
C+133 = 180
C = 180-133
C = 47
Angle C is adjacent to the exterior angle B, meaning
B+C = 180
B+47 = 180
B = 180-47
B = 133

A store is having a 20%-off sale on all pairs of shoes. Kurt wants to buy a pair of shoes that have a regular price of x dollars. The sales tax is 7%. Which expression represents the final price of the shoes?
Answer:
[tex]\$ \ \dfrac{428}{500}x[/tex]
Step-by-step explanation:
Regular price of a pair of shoes = $[tex]x[/tex]
Discount offered = 20%
Amount of discount offered = 20% of $[tex]x[/tex]
Discounted price = Regular price - Amount of discount
Discounted price = $[tex]x[/tex] - 20% of $[tex]x[/tex] = 80% of $[tex]x[/tex] = [tex]\$ \frac{4}{5}x[/tex]
Now, it is given that there is a sales tax of 7% as well on the price.
Sales tax is applied on the discounted price.
Therefore, sales tax = 7% of [tex]\$ \frac{4}{5}x[/tex]
Final Price after applying the sales tax = [tex]\$ \frac{4}{5}x[/tex] + 7% of [tex]\$ \frac{4}{5}x[/tex]
[tex]\Rightarrow 107\%\ of\ \$\ \ \dfrac{4}{5}x[/tex]
[tex]\Rightarrow \$ \ \dfrac{428}{500}x[/tex]
Therefore, the expression to represent the final price of the pair of shoes:
[tex]\$ \ \dfrac{428}{500}x[/tex]

Answer:
[tex]27[/tex]
Step-by-step explanation:
A rhombus is a quadrilateral where all sides are equal in length. This means that [tex]\overline R \overline O = \overline O \overline C[/tex].
From this, we can write:
[tex]2x-15=x+6[/tex]
[tex]x-15=6[/tex]
[tex]x=21[/tex]
Now that we have solved for [tex]x[/tex], we can find the length of [tex]\overline R \overline O[/tex] by using substitution:
[tex]2x-15=2(21)-15[/tex]
[tex]=42-15[/tex]
[tex]=27[/tex]

A store sells posters for $12.50 each and picture frames for $30.00 each. One day, the store sells a total of 32 posters and
picture frames combined for a total of exactly $645.00.
How many posters and picture frames does the store sell on that day?
O 13 posters and 16 picture frames
14 posters and 18 picture frames
16 posters and 16 picture frames
18 posters and 14 picture frames
Answer:
D
Step-by-step explanation:
Answer:
option D: 18 posters and 14 picture frames
Step-by-step explanation:
It isn't the first one because it doesn't have a total of 32 combined sales
It isn't the second because the total money is $715.00
It isn't the third because the money totals out to $680.00
The answer is the fourth option because the total product sold is 32 and the total money earned is $645.00

Members of a baseball team raised $1199.50 to go to a tournament. They rented a bus for $830.50 and budgeted $30.75 per player for meals. Determine the number of players the team can bring to the tournament.
Answer:
The team can bring 12 players to the tournament.
Step-by-step explanation:
With the information provided, you can say that cost of going to a tournament is equal to the cost of renting the bus plus the result of multiplying the cost per player for meals for the number of players, which is:
c=830.50+30.75x, where:
c is the cost of going to a tournament
x is the number of players
Now, you can replace c with $1199.50 that is the total amount they raised and solve for x:
1199.50=830.50+30.75x
1199.50-830.50=30.75x
369=30.75x
x=369/30.75
x=12
According to this, the answer is that the team can bring 12 players to the tournament.
