Can someone help me with this please???

Answer:
C=2.39+0.89m
The amount is correct. An international call for 26 minutes costs $25.53
Step-by-step explanation:
The phone charge is equals to $2.39
Plus additional 0.89 per minute
m=minutes
Total cost = phone charge + 0.89m
C= $2.39+0.89m
To calculate the total cost after 26 minutes, replace m with 26
C=$2.39+ 0.89x26 (0.89x26=23.14)
C=$2.39+23.14
C=$25.53
The amount is correct. The total cost for an international call for 26 minutes is $25.53
