Answer:1800 - 1350= 450 3 months after the purchase he payed $450

450/3= $150 per month

1350 - 1050= 300 5 months AFTER THE PURCHASE he payed $300

300/2= $150 per month

^after 2 more months he payed $300^

$150 per months

Equation: (initial amount) - (150)M

M= amount of months after purchase

B = 1800 - 150M
