Question

Jill has $340 in her savings account and makes $12.50 an hour but can work no more than 40 hours a week. She only gets paid at the end of the week. How many weeks will it take her to have $850?

Answer 1

Answer: 2 weeks

Explanation:

Given: Amount in the saving account = $340

Hourly wage = $12.50

Maximum number of hours Jill can work = 40

Amount she can make by working 40 hours in a week = $ (40 x 12.50 )= $ 500

Let x be the number of weeks.

The according to the question , we have

`500x+340\geq850\\\\\Rightarrow\ 500x \geq850-340\\\\\Rightarrow\ 500x \geq510\\\\\Rightarrow\ x \geq(510)/(500)\\\\\Rightarrow\ x \geq1.02`

i.e. x=2

So, it will take 2 weeks to have $850.
