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.
