Answer:
$46.2
Step-by-step explanation:
If kevin is paid $8.80 per hour and he worked 7 hours, we need to multiply the hourly pay by the number of hours worked:
$8.80(7) = $61.6
In total I earn the amount of $61.6.
He gave 1/4 of this earnings ti his mother.
1/4 of $61.6 is:
so he gave $15.4 to his mother.
what he has left is the subtraction of what he earned and what he gave his mother:
$61.6 - $15.4 = $46.2
He has $46.2 left
