the accountant charged $35 for the first hour of work and $23 for each hour he did after that he earned a totL or $127 how many hours did he work

Answers

He worked 5 hours in total: 35$ for the first hour, + 23 + 23 + 23 + 23 = 127$ for five hours of work.

The amount charged by the account in the first hour = $35
The amount charged by the accountant after first hour = $23
Total earnings of the accountant = $127
Let us assume that he worked for = x hours
then
35 + 23x = 127
23x = 127 - 35
23x = 92
x = 4
So from the above deduction we can conclude that the accountant worked for 4 hours. I hope the procedure is simple enough for you to understand.
