Question

For her birthday, Sarah’s parents got her a new phone. The phone’s plan costs $59.99 a month and allows for unlimited calls, unlimited web access, and 100 text messages a month. In addition, each text message over the 100 included with the plan is $0.10. If Sarah’s parents budget $78.00 a month for her cell phone bill, what is the maximum number of text messages that she can send in one month?
A. 181
B.280
C.880
D.700

Answer 1

they have 78.00 to spend per month for her plan
plan costs 59.99
78.00 - 59.99 = 18.01
each text after 100, you spend .10
100 + .10x
if she sends 180 texts after 100, she pays 18 dollars ( .10(180) = 18)
So the max she can send is 100 + 180 = 280
