$6.85
$7.75
$7.85
$8.75
none

1 answer

To find out how much the boy will have left after paying his mother, we need to subtract the amount he owes from the amount he earned.

He earned: $12.50
He owes: $5.75

Now subtract the amount he owes from what he earned:

\[ 12.50 - 5.75 = 6.75 \]

So, after he pays his mother, he will have $6.75 left. Since $6.75 is not among the options given, the answer is none.
