radius = 5.75 units

circumference = 36.11 units

Area = 103.81625 square units

kykrilka [37]

Given:

Amount spent on 2 DVDs = $41.75

Sales tax = $3.15

Coupon = $1.00 off

To find:

The cost of each DVD.

Solution:

Let x be the cost of each DVD.

Then, cost of two DVDs = 2x

Amount spent of 2 DVDs = Cost of 2 DVDs + Sales tax - Coupon discount

$41.75=2x+3.15-1.00$

$41.75=2x+2.15$

$41.75-2.15=2x$

$39.6=2x$

Divide both sides by 2.

$\dfrac{39.6}{2}=x$

$19.8=x$

Therefore, the cost of each DVD is $19.8.
