Question

A carpenter earns $256 working on a 4-hour repair job. The next repair jobs, billed at the same rate, are a 3-hour

job followed by a 2-hour job.
How much does the carpenter earn for the three jobs together?
$192
$320
$384
$448
$576

Answer 1

$448

Explanation:

The carpenter earns $64 per hour ($256/4 hours).

For the 3-hour job, the carpenter will earn $192 ($64/hour x 3 hours).

For the 2-hour job, the carpenter will earn $128 ($64/hour x 2 hours).

Therefore, for the three jobs together, the carpenter will earn $256 + $192 + $128 = $576.

Hence, the correct option is $448.
