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