Answer:
$225
Explanation:
Carlos spends 25 hours helping his friend to build a fence and he was paid $187.50
We have to first calculate the amount for each hour worked
25hr= 187.50
1hr= x
x= 187.50/25
= 7.5 hours
Therefore if he works for 30 hours he will earn
7.5× 5
= 37.5
= 187.50+37.5
= $225
Hence if he works for 30 hours he will earn $225
