You want to buy the bicycle that is $116. you already have $43.50 saved and plan to save an additional $7.25 every week.
part a: write and solve an equation to find the number of weeks you need to save before you can purchase the bicycle.
part b: how much sooner could you purchase the bicycle is you had a coupon for $20 off and saved $8.75 every week? explain your reasoning.
! i'm in 7th i need to get my math home work done, and my parents ar'nt home to mee.. you!

A. since you already have $43.50 already saved you subtract that from the amount the bike cost so you can see how much more needs to be left to save and that gives you $72.50. Then you divide the amount your saving up every week from that. So $72.50 divided by $7.25 is 10 and thats how many weeks it will take to save.

B. Since you still have that $43.50 saved and you have a coupon for $20 dollars off . Add those together to see how much you have saved up which equals $63.50. The bike is $116 so you subtract the amount you have for the bike from $116 which is $63.50 and that equals $52.50 and thats how much more money you need. Then divide how much money needed by the amount your saving up a week, which is $8.75. So $52.50 divided by $8.75 is 6 and thats how many weeks it will now take to get the bike.

Iwould say rat and vsu but i’m not 100% sure
