Question

Kehlani is saving up to buy a new bicycle. She already has $80 and can save an additional $9 per week using money from her after school job. How much total money would Kehlani have after 7 weeks of saving? Also, write an expression that represents the amount of money Kehlani would have saved in w weeks.

Answer 1

Kehlani saves $9 each week. After 7 weeks she saves 9×7 = $63 more. Total = 80 + 63 = $143.

An expression for the total after w weeks is 80 + 9w. (The amount saved during w weeks alone is 9w.)
