Question

Patricia wants to buy a pair of jeans for $240. She has saved $30 each week for 3 weeks. How many more weeks does Patricia need to save money if she continues to save $30 each week?

Answer 1

Since Patricia already saved $30 each week for 3 weeks, she already saveld a total of:

`3\cdot30=90`

$90.

So, from the $240 total it is still left for her to save:

`240-90=150`

$150.

Since she will continue to save $30 per week, we can divide 150 by 30 to get the total number of weeks she needs:

`(150)/(30)=5`

So, this means she needs to save money for 5 more weeks.
