Question

a long distance call costs $.50 for the first minute and y cents for additional minute. How much does each additional minute cost if the bill was $5.60 and you talked for 10 minutes

Answer 1

$.56

Explanation:

The first minute is .50 cents and the subtotal was 5.60. Subtract for the first minute to get the subtotal for 9 minutes.

(5.60-.50=5.10)

5.10 is the amount for 9 minutes so now we will divide to get the price for each minute.

(5.10÷9=.56)

This means each minute after the first minute is $.56 cents.
