Answer:
The amount earned is $327.75
Step-by-step explanation:
If the workwr working for 5h gets $71.25, then his working for 1 hour could be said to be x.
5h = $71.25
1h = x; cross multiplying would result in
x= ![\frac{($71.25*1)}{5h}](https://tex.z-dn.net/?f=%5Cfrac%7B%28%2471.25%2A1%29%7D%7B5h%7D)
x= $14.25 which is the pay for 1h
Therefore for 23 h the worker would earn
23* 14.25 = $327.75
Let x = the boys
3x = the girls
x + 3x = 180
4x = 180
4x/4 = 180/4
x = 45 boy's profit.
3x = 3(45) = 135 girl's profit.
