Question

write an equation that will solve this problem: Together a house and a lot cost $400,000. The house cost seven times as much as the lot. how much will the lot cost? how much will the house cost?

Answer 1

Hi

House = H
Lot = L

H+L = 400,000
H = 7L

7L+L = 400,000
8L = 400,000
L = (400,000)/8
L = 50,000

H = 7L
H = 7(50,000)
H = 350,000

Answer:

Lot cost: $ 50,000
House cost: $ 350,000
