Answer :
Answer:8 weeks
Step-by-step explanation:
So here is our equation for your question: 125 + 15x = 245
You then have to subtract 125 from both sides so we can isolate our variable which will give us 15x = 120 . Divide 15 from both sides : 15x/15 = 120/15 which will give us x = 8.
So it will take 8 weeks for her to buy a bike.
