Question

James has $325 in his savings account. He spends $28 a week. How many, w, weeks until he has $157 left in his account?​

Answer 1

6 weeks

Explanation:

Total savings= $325

For every week, his total savings decrease by $28.

Let's form an expression for the amount of money left in his account after w weeks.

325 -28w= 157

28w= 325 -157

28w= 168

Divide by 28 on both sides:

w= 168 ÷28

w= 6

Thus, there are 6 weeks until he has $157.
