Answer:
The Total number of min call he use his phone is 234 minutes .
Explanation:
Given as :
The Total phone bill cost = $47.43
The fixed charge of cellular plan = $9.99
The per min phone charge = $0.16 per min
Let The number of minutes did he use his phone = n min
Now, According to question
The Total phone bill cost = The charge of cellular plan + The per min phone charge × The number of minutes did he use his phone
Or, $9.99 + $0.16 × n = $47.43
Or, $0.16 × n = $47.43 - $9.99
Or, 0.16 × n = 37.44
∴ n =
![(37.44)/(0.16)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/p2btq7pvfovcjffnydkhzl6kepc5esdpg5.png)
I.e n = 234 min
So, number of minutes of call = n = 234 min
Hence The Total number of min call he use his phone is 234 minutes . Answer
