Home Depot gives contractors a 10% discount on all orders. After the discount, a contractor pays $342 for plywood. What was the original cost of the plywood?
Answer provided by our tutors
let 'x' represent the original cost, then "-0.10x" is a 10% discount:
342 = x - 0.10x
x=380
The original cost of the plywood was $380.
