Answer:
The cost of each DVD is $11.8 .
Step-by-step explanation:
Let us assume that the cost of one DVD be x.
As given
Hector spent $25.75 for 2 DVDs that cost the same amount.
The sales tax on his purchase was $3.15.
Hector also used a coupon for $1.00 off his purchase.
Than the equation
Total Hector Spents for two DVDs = 2 × cost of one DVD + Sales tax + Coupon cost .
Putting the value
25.75 = 2x + 3.15 - 1.00
25.75 = 2x +2.15
25.75 - 2.15 = 2x
23.6 = 2x
[tex]x = \frac{23.6}{2}[/tex]
x = $11.8
Therefore the cost of each DVD is $11.8 .
