To solve this problem, solve the polynomial that describes the situation.

If Kevin deposits three paychecks, each for $225.75, he will have 3 times 225.75.

If he makes two payments, each for $75, he has to substract 2 times 75.

And finally, the third payment is for 125, it means he has to substract 125.

Solve the polynomial:


\begin{gathered} 3\cdot225.75-2\cdot75-125 \\ 677.25-150-125 \\ 402.25 \end{gathered}

The approximate change in Kevin's account is $402.25.
