Question

Comed charges $40 for a phone and $30 a month for its economy plan/ The equation c= 30t +40 describes the total cost, c, of operating a comed phone for t months.

What is the total amount for two months of service?


If a customer has only $110 available how many months of service can he recieve?

Answer 1

c = 30 t + 40
c = 60 + 40
c = 100
Cost for two months = $100

100 = 30t + 40
30t = 60
t = 2
He can receive 2 months service.

Answer 2

ok

$30 x 2 = $60
$40(one-time charge for the phone)

$60
+$40= $100

Total amount for two months is $100 dollars.
The customer can only recieve 1 month's service.

Answer 3

2 months of service = 100 dollars.
30t+40=c
30(2)+40=100
30*2=60
60+40=100

Answer 4

at 2 months t = 2

so cost c = 30*2 + 40 = 60 + 40 = $100

Since the next month cost $30, and he only has $110, he can only afford two months.

Answer 5

sounds like u are pretty lazy because this is a simple problem.

c=30t+40
c=30*2+40
c=60+40
c=100

100 dollars for 2 months of service.

only 2 months of service for 110 dollars.
