At a certain store, the taco sauce was on sale for 1/5 off. With a coupon for an additional 40 cents off, the final cost of the
sauce was $1.20.
Which equation will help Marvin to figure out how much his payment will be?
Let x = one installment
A) c - 1/5c + 40 = 120
B) c - 1/5c - 40 = 120
C) 1/5c = 120 - 40
D) 1/5c = 120 + 40
1 answer:
B) c - 1/5c - 40 = 120
c- (original cost) - 1/5c (sale) - 40(coupon)= 120(final cost)
Hope that helps! :)
