    A. 15w+90=285 can be used to determine the number of weeks it will take for Ken to repay the entire amount.

    B. It will take Ken 13 weeks to repay the entire amount.

    Step-by-step explanation:

    Money borrowed = $285

    First repay = $90

    Per week repay = $15

    Let,

    w be the number of weeks, therefore,

    A. Write an equation that can be used to determine w, the number of weeks it will take for  Ken to repay the entire amount.

    Money borrowed = First repay + Per week repay * number of weeks

    285 = 90 + 15w

    15w+90=285   Eqn 1

    15w+90=285 can be used to determine the number of weeks it will take for Ken to repay the entire amount.

    B. What number of weeks will it take Ken to repay the entire amount?

    Solving Eqn 1: Subtracting 90 from both sides

    15w+90-90=285-90\\15w=195

    Dividing both sides by 15

    \frac{15w}{15}=\frac{195}{15}\\w=13

    It will take Ken 13 weeks to repay the entire amount.
