Let x be the number of hours the apprentice works.
Then the master electrician works x + 3 hours.
The total amount paid to the apprentice is $40x.
The total amount paid to the master electrician is $62(x + 3).
And the total amount paid to both is $492.
Therefore, $40x + $62(x + 3) = $492.
Solve for x:
$40x + $62x + $186 = $492
$102x = $306
x = 3
The master electrician works x + 3 = 6 hours.
Therefore, the master electrician earns $62 * 6 = $372.
Therefore, the correct answer is D) $372.
A master electrician earns $62 per hour. His apprentice earns $40 per hour. The master electrician works 3 hours more than the apprentice. If together they are paid $492, how much does the master electrician earn?
