Question

Leroy took a trip to Alaska. His airfare was $243 and he spent $72 each day while

he was there. Which expression can he use to help him find the cost of the trip?
(x = number of days spent in Alaska) *

Answer 1

Total cost of the trip = 243 + 72x

Explanation:

Cost of airfare = $243

Amount spent per day = $72

Which expression can he use to help him find the cost of the trip?

Let

x = number of days spent in Alaska

Total cost of the trip = Cost of airfare + (Amount spent per day * number of days spent in Alaska)

= 243 + (72 * x)

= 243 + 72x

Total cost of the trip = 243 + 72x

If he spent 4 days on the trip

Total cost of the trip = 243 + 72x

= 243 + 72(4)

= 243 + 288

= $531
