Michelle needs to save $12/week for 13 weeks to save enough money for the trip.
Given:
Michelle wants to save $150 for the trip
She saves $12/week
Question:
How many weeks will it take her to save enough money for the trip?
to find out how many weeks it takes to save $150
= The total saving : saving/week
[tex]\boxed {= \frac{150}{12} = 12\frac{1}{2} }[/tex] weeks
We need to round up the result to 13 weeks, because if she saves for 12 weeks she will only get (12 x $12 = $144), but if she save up to 13 weeks she will get (13 x $12 = $156)
