The correct answer would be j (18) because all you have to do is keep adding 0.17 and keep counting until you get to the 2.50 mark. I hope I helped you
Answer:
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
