To save money, you put $200 in your bank account each week. After saving for 4 weeks, you have $1,700$ dollars in your account. Which equation models your savings account balance at the end of each week?

Question

A.) y-4=200(x-1700)
B.) y-1700=200(x-4)
C.) y-200=1700(x-4)
D.) y-1700=200(x+4)

Answer 1

y = amount at end of every week after 4 weeks = 1700 + 200 (x-4)
so

y - 1700 = 200(x-4)
