Acertain internet provider charges 16.95 for 150 hours of usage per month and 0.95 for each additional hour. if marc was online for 200 hours last month, what was his bills for that month?

SO the first step you would do in this equation is to subtract 200 by 150:
200 - 150 = 50
Next, you would multiply 0.95 by 50 =
0.95 x 50 = 50.95
Now that we know how much money he for the extra 50 hours we can add 50.95 with 16.95:
50.95 + 16.95 = 67.9
SO Marc's internet bill was $67.90
