Question

Each day that Kevin rides the train to work, he pays $2.50 each way. If Kevin takes the train to work and back 3 times, which amount represents the change in his money?

Answer 1

If Kevin takes the train to work and back 3 times, the change in his money would be $5.

Step-by-step explanation:

Each day that Kevin rides the train to work, he pays $2.50 each way. So, for a round trip, he would pay $2.50 x 2 = $5. If Kevin takes the train to work and back 3 times, the total amount he would pay is $5 x 3 = $15. Therefore, the change in his money would be the difference between the total amount he pays and the amount he initially had. If he had $20 initially, then the change in his money would be $20 - $15 = $5.
