2.5(12.75x + 24.50) = 188.75
31.875x + 61.25 = 188.75
31.875x = 188.75 - 61.25
31.875x = 127.50
x = 127.50 / 31.875
x = 4....they worked 4 hrs
31.875x + 61.25 = 188.75
31.875x = 188.75 - 61.25
31.875x = 127.50
x = 127.50 / 31.875
x = 4....they worked 4 hrs
The number of hours did they work is 4 hours.
Given that,
- The initial fee of $24.50 plus $12.75 an hour.
- And, it charged 2.5 times the regular amount.
- The total amount is $188.75.
Based on the above information, the calculation is as follows:
2.5(12.75x + 24.50) = 188.75
31.875x + 61.25 = 188.75
31.875x = 188.75 - 61.25
31.875x = 127.50
[tex]x = 127.50 \div 31.875[/tex]
x = 4 hours
Therefore we can conclude that the number of hours did they work is 4 hours.
