Question

The cost of travel insurance in pounds (C) is worked out using the equation: C = 10 + 20(x – 1)

x is the number of weeks that a customer is travelling for.

A customer wants travel insurance for 6 weeks.

How much should the customer be charged?

Answer 1

Answer: 110 pounds

C = 10 + 20(6 - 1)
C = 10 + 20(5)
C = 10 + 100
C = $110
