A jacket sells for $24.99. All the merchandise in the store is on sale at a 25% discount. If the sales tax is 8%, what will a customer pay for the jacket?

Answers

Answer:

$20.24

Step-by-step explanation:

Since the 25% discount takes off a quarter of the price, we multiply 24.99 by 3/4

24.99 x 3/4 = 18.74

So with the discount and without tax, the cost of the jacket is 18.74

Then we add 8% for sales tax

8% of 18.74 is $1.50

18.74 + 1.5 = 20.24

So the final cost of the jacket is $20.24

Find the area of the trapezoid

Answers

Count the number of Little boxes there are on each side Like I did in the picture below. Then separate the triangle and the rectangle so that you can find the area of the rectangle first which you can figure out with just doing base times height. Then find the area of the triangle which is base times height divided by 2. The area of the rectangle should be 20 and the area of the triangle should be 6. Then you just add the two together so the area of a trapezoid should be 26. Now this is the area of the trapezoid not the perimeter. Perimeter and area are different things to find the perimeter you just count the outside lines of the trapezoid so it would be 5+4+5+3 Plus the long side of the triangle which you find by using Pythagorean theorem (A squared plus B squared equals C squared) I also show this in the picture below.

Robin braided g inches of a friendship bracelet. Olivia braided 12 less than 1/3 the number of inches Robin braided. Select all of the expressions that represent the total number of inches braided by Robin and Olivia.


A. 2/3g - 12

B. 4/3g - 12

C. 4(1/3g - 3)

D. 1/3(4g - 36)

E. g + ( 1/3g - 12)

Answers

Answer: C. [tex]4(\dfrac13g-3)[/tex]

Step-by-step explanation:

Given: Robin braided g inches of a friendship bracelet.

Number of inches braided by Olivia = [tex]\dfrac13g-12[/tex]

The total number of inches braided by Robin and Olivia = Number of inches braided by  Robin + Number of inches braided by Olivia

[tex]=g+\dfrac13g-12\\\\=\dfrac43g-12\\\\\=4(\dfrac13g-3)[/tex]

The total number of inches braided by Robin and Olivia = [tex]4(\dfrac13g-3)[/tex]

Hence, C. is the correct option.

There are 195 adults and 320 children at a zoo. The zoo makes a total of $6,515 from the entrance fees, and the cost of an adult and a child to attend is $27, how much does it cost each for a parent and a child? Let a represent an adult. Let c represent a child. Enter a system of equations to represent the situation, then solve the system.

Answers

Answer:

a+c=27

195a+320c=6515

Step-by-step explanation:

adult (a): 195

children (c): 320

total $: $6515

child $: 27

a+c=27 --> c=-a+27

195a+320c=6515

sub the first equation into the 2nd equation to get a=17

sub a=17 into c=-a+27 to get c=10

so, an adult ticket is $17 and a child ticket is $10.

Why?

It states in the problem itself that miles types 35 words per minute.
