12 the cost of a telephone call is $0.60 for the first three minutes plus $0.17 for each additional minute. what is the greatest number of whole minutes the telephone call can be if the cost cannot exceed $2.50?
f 8
g 11
h 14
j 18

H

Step-by-step explanation:

The total cost of the call is $2.50

Since the first three minutes cost $0.60

x minutes = $2.50 - $0.60

x minutes = $1.9

Each additional minutes cost $0.17

So: $1.9 / $0.17 = 11

To find the total minutes

$0.60 + $1.9 = $2.50

3 + 11 = total minutes

14 = total minutes

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
