Question

A phone company charges 0.1 per minutes talked and additional $24 for services each month. Write the liner function C(n) where n is the amount of minutes talked and c is the cost in dollars per month.
a) what is the cost if you talk for 15 minutes?


b) if you have a budget of $50 dollars, how many minutes can you talk per month?

Answer 1

Answer:

the cost of talking for 15 minutes would be $1.5

15x0.1=1.5

for $50 you could talk for 500 minutes.

50/0.1=500

double check, 500x0.1=50
