Question

Nick opens a savings account with $50.Each week after,he deposits $15.In how many weeks will he have saved$500?

Answer 1

Answer: 31 weeks

Explanation:

50 + 15w = 500

w = weeks

50 + 15w = 500

-50

15w = 450

/15

w = 30

So 30 weeks after the first 50 makes 31

Answer 2

30 weeks

Explanation:

if his account has 50$ in the first place, this means we subtract 50$ from 500$

500-50= 450

now we have 450, we divide 450 to 15(the money he deposits per week).

450÷15=30

the answer is 30 weeks
