Answer: A. $5 × 25
Step-by-step explanation:
Given the following :
Number of cartons of specialty paper ordered = 24 cartons
Regular price for a carton = $6.88
Discount given off each carton = $1.75
Hence,
Discounted price per carton = $(6.88 - 1.75) = $5.13
Actual amount to be paid for the order :
Discounted price * number of cartons to be ordered
$5.13 * 24
Hence, a reasonable estimate will be :
$5.13 = $5( nearest whole number)
24 can be rounded to 25 (this covers for the $0.13 on the discounted cost per carton)
Reasonable estimate :
$5 × 25
Caillan's pocket money increased 20-15=5 dollars per week, or to 20-15=1.33 of it's original amount. This is a 33% increase.
3.21 kilometers is the answer to this question.
We want to solve

Subtract 2/(2x+1) from each side.

Add 1/4 to each side, and simplify the left side.

Cross multiply.
4(x - 2) = 1(2x + 1)
4x - 8 = 2x + 1
Simplify and solve for x.
4x - 2x = 1 + 8
2x = 9
x = 9/2 or x = 4 1/2.
