2.1 - 2.2 Practice TEST

Question

A phone company offers two monthly charge plans. In Plan A, the customer pays a monthly fee of $20 and then an additional 7 cents per minute of use. In Plan B, the customer pays a monthly fee of $38 and then an additional 4 cents per minute of use.

Answer 1

Let's use m to represent the number of months and n to represent the number of minutes.

In plan A, for every month, you will be paying $20. So, we get 20m and for every minute you will be paying 7 cents so we get .07n. To get the total cost of the plan, we add the two.

Plan A - 20m + .07n

In plan B, for every month, you will be paying $38. So, we get 38m and for every minute you will be paying 4 cents so we get .04n. To get the total cost of the plan, we add the two. '

Plan B - 38m + .04n
