Question

A student is saving up for a new iPhone. He currently has $295 and can save $75 a week. Write and equation that represents his initial savings and his weekly savings rate (s) and the total (t) that he has saved at any particular time

Answer 1

an equation is t = 75s + 295

Answer 2

Write and equation that represents his initial savings and his weekly savings rate

Initial savings = $295

Savings per week = $75

Let the number of savings made per week = weekly savings rate be s

so weekly savings = 75 x s = 75s

Hence the total (t) that he has saved at any particular time =

`T=295+75s`
