Answer:
$.56
Step-by-step 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.
