Answer:
$11,000
Step-by-step explanation:
Using one variable and an expression, you can set up an equation to solve for the cost of both the lot and the house.
x = the cost of the lot
7x + 1000 = the cost of the house since the houses costs ($1000 more than seven times the cost of the lot)
Since the cost of the house and lot together is more than $89,000:
x + 7x + 1000 > 89,000
Combine like terms: 8x + 1000 > 89,000
Subtract 1000 from both sides: 8x + 1000 - 1000 > 89,000 - 1000 or 8x > 88000
Divide by 8 on both sides: 8x/8 > 88,000/8
x > $11,000
