Answer:
Step-by-step explanation:
Let the number of months = x
Cost = constant + monthly payment
Cost = 1000 + 1500x for apartment A
Cost = 1200 + 1475*x for apartment B
You want the costs to be equal, so
1000 + 1500x = 1200 + 1475x Subtract 1000 from both sides
1500x = 1200 - 1000 + 1475x Combine the right
1500x = 200 + 1475x Subtract 1475 from both sides
1500x - 1475x = 200 Combine
25x = 200 Divide by 25
x = 200/25
x = 8
After 8 months each apartment will cost the same amount.
How much is that
C = 1000 + 1500 *8
C = 1000 + 12000
C = 13000
