Question

The cost of a plane ticket varies directly as the number of miles in the trip. A 3000 mile trip costs $400. What is the cost of a 450 mile trip

Answer 1

Answer:

$60

Step-by-step explanation:

set up a proportion and cross-multiply:

3000/400 = cost/450

c = cost

3,000c = 180,000

c = 180/3

c = 60
