Kevin has a checking account. This month he deposits three paychecks. Each paycheck is for $225.75. He also makes two payments for utilities. Each payment is for $75. He makes a third payment for $125. What is Kevin's new account balance?

402.5 (if this wrong then sorry)

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
