Jennifer's saving to buy a bike. The bike costs $245. She has $125 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 8 weeks to save up enough money for the bike.
To get the answer first you have to subtract 125 from 245 to see how much money she still has to save then divide the answer which is 120 by 15 and you get 8. Hope this helps!!
So... 245=15x+125 x equals the total number of weeks Lets solve! 245=15x+125 Subtract 125 from both sides 120=15x Divide 15 from both sides x=8 Jennifer will have enough money to buy a bike in 8 weeks
