Question

Dan borrows $230 from his brother to buy a lawn mower. He will repay $65 to start, and then another $15 per week.

The equation that can be used to determine w, the number of weeks it will take for Sierra to repay the entire amount is:



230 = 65(_____a_______ ) + 15(______b______ )



How many weeks will it take Sierra to repay the entire amount? _____c_______

Answer 1

Explanation:

I find a better equation would be 230-65=Ans÷15. This is because if we subtract the initial payment from the total he needs to pay we can easily divide that number by fifteen dollars to find how many weeks it will take. When we subtract 230-65 we get 165, which can then be in turn divided to get the answer of 11 weeks to repay the lawnmower.
