Answer:
Single Equivalent Discount % on final price = 41.58%
Explanation:
The grill was initially priced at $769.99 and was discounted to $550.54 which is 28.5% ((550.54/769.99)-1)*100
and then further discounted by 18.3% ((449.79/550.54)-1)*100 to $449.79.
but if we want to get the single discount rate for $449.79 (final price), we have to compare it with very first original price of $769.99 so the formula will be:
((449.79/769.99)-1)*100 = 41.58% which shows the actual discount % versus the original price of the grill.

A local hamburger shop sold a combined total of 486 hamburgers and cheeseburgers on Sunday. There were 64 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Sunday?
Answer:
Step-by-step explanation:
h and c are the numbers of hamburgers and cheeseburgers, respectively.
“a combined total of 486 hamburgers and cheeseburgers”
h + c = 486
“64 fewer cheeseburgers sold than hamburgers”
c = h - 64
Substitution:
h + (h-64) = 486
2h = 550
h = 275
275 hamburgers were sold

Sarah and Connor went bowling together. Sarah rented bowling
shoes and played three games, for a total cost of $9.50. Connor
rented bowling shoes and played five games, for a total cost of
$14.50.
How much does it cost to rent bowling shoes?
Answer: The cost to rent bowling shoes is $2.
Step-by-step explanation:
Let's define:
S = cost for renting bowling shoes.
G = cost per game.
Then if you rent shoes, and play x games, the total cost is:
C = S + x*G
We know that Sarah rented the shoes and she played 3 games, paying a total of $9.50, then:
C = $9.50 = S + 3*G
We also know that Connor rented the shoes and played 5 games, with a total cost of $14.50
C = $14.50 = S + 5*G
Then we have a system of equations.
$9.50 = S + 3*G
$14.50 = S + 5*G
To solve this, we first need to isolate one of the variables in one of the equations. I will isolate S in the first one:
S = $9.50 - 3*G
Now we can replace this on the other equation:
$14.50 = ($9.50 - 3*G) + 5*G
$14.50 - $9.50 = 5*G - 3*G
$5 = 2*G
$5/2 = G
$2.50 = G
Then each game costs $2.50
The cost to rent bowling shoes can be found with any of the two equations, for example i will use:
S = $9.50 - 3*G
Where we replace G by the value we found above.
S = $9.50 - 3*$2.50 = $2
S = $2.
The cost to rent bowling shoes is $2.

15) Volume of a cuboid with base area 500 m2 and height 4m is. with steps
Answer:
Volume of cuboid = 2000 m³
Step-by-step explanation:
Given the following data;
Base area = 500 m²
Height = 4m
To find the volume of a cuboid;
The volume of a cuboid is given by the formula;
Volume of cuboid = length * breadth * height
But remember, base area = length * breadth
Therefore, the volume of the cuboid becomes;
Volume of cuboid = base area * height
Substituting into the equation, we have;
Volume of cuboid = 500 * 4
Volume of cuboid = 2000 m³

Answer:
222 ft
Step-by-step explanation:
add 15 ft to each side of the length and width
L = 28 + 30 = 58
W = 23 + 30 = 53
perimeter = 2(L + W) = 2(58 + 53) = 222 ft
Answer:
222 ft
Step-by-step explanation:
The fence must be 15x2 (30) feet wider and 15x2 (30) feet longer, since the fence must be 15ft away at all points. Take 23+30 to find width, and take 28+30 to find length. You get that the fence is 53 ft. wide and 58 ft long. Feet of fencing is the same as asking for perimeter, so 53+53+58+58=222 feet of fencing

Answer:
Step-by-step explanation:
root(23) - 8 < root(23) - 3 -3 is greater than -8
3 root(62) > 3 root(59) 62 > 59 Since the numbers are positive the roots of the larger number is going to be larger than the roots of the smaller number
-root(50) < - 3
The root of 50 is about 7. - 7 is smaller than - 3. Think money. Would you rather pay 3 dollars for a cup of coffee than 7 dollars for a cup of coffee?
root 15 + 2 < root(65) - 1
root(15) is roughly 4 when 2 is added to it, the result is about 6
root (65) is a touch over 8. When 1 is subtracted the result is about 7.
That's larger than the left side.
