Answer:
6 weeks
Explanation:
First, if the bike is $223 and if Jennifer has 115 saved, then you have to do 223 - 115 which gets you 108.
Second, if you need $108, and you make $18 every week, then you would do 108/18 which gets you 6.
Therefore, it would take Jennifer 6 weeks to buy the bike.
Hope this helps!
