Hector spend $33.75 for 2 DVD 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. How much did each DVD cost?

Respuesta :

Answer:

15.8 dollars per dvd.

Step-by-step explanation:

Our equation for this problem is:

v = how much one dvd costs

2v + 3.15 - 1 = 33.75

2v +3.15 =34.75 (added 1 on both sides)

2v = 31.6 (subtracted 3.15 from both sides)

v = 15.6 (divided by 2 on both sides)
