Jennifer is saving money to buy a bike. The bike costs $326. She has $131 saved, and each week she adds $15 to her savings. How long will it take her to save enough money to buy the bike ? It will take her blank weeks to save for the bike. How many weeks ?

It should take her 13 weeks.

Step-by-step explanation:

If the bike costs $326 and she already has $131, we can subtract 131 from 326. 326-131=195. Now we know that Jennifer needs $195 dollars. Next, since she adds $15 each week, divide 195 by 15. 195/15= 13. It should take Jennifer 13 weeks so save up for her bike.
