A cell phone plan charges $15 per month for 300 text messages. The plan charges $0.08 for each additional text message. You use 60 additional texts this month. What is your bill for the month?

Respuesta :

60 x 0.08 = 4.8

15.00 + 4.80 =

$19.80
0.08x60= 4.80 + 15 =19.80 
so 19.80 is the biil for the month
