Answer:
Let x represent the amount of weeks she is saving up for the bike, and y represents the cost of the bike.
The equation would look like this:
So, let's say the bike costs $2000.
Divide 2000 by 20, and it will give you the x value (or, the amount of weeks it will take)
It will take 100 weeks for her to save $2000 for the bike, if she puts back $20 each week.
The answer would be 5,400 ( 3000 times 0.15 would be 450 then, 450 times 12 is 5,400.)
It's da last answer good luck but if it is wrong dnt sue me lol
