A cell phone plan costs 20 dollars each month, plus 5 cents per text message sent, plus 10 cents for each minute used over 30 hours. In January Michelle sent 100 text messages and talked for 30.5 hours. How much did she have to pay?

A. 24
B. 24.5
C. 25.5
D. 28
E. 30


Text messages = 100
Call made = 30.5 hours = 30 hours and 30 minutes


Total Payment = 20$ + 100*0.05 + 0.1*30 = 20 + 5 + 3 = 28$
