Final answer:
Amanda would have to work 7 hours to make $133.
Step-by-step explanation:
To find out how many hours Amanda would have to work to make $133, we can set up a proportion using the given information. We know that she made $247 for 13 hours of work, so we can set up the proportion:
13 hours / $247 = x hours / $133
To solve for x, we can cross multiply:
13 * $133 = $247 * x
Simplifying, we get:
$1,729 = $247x
Dividing both sides by $247, we find that x = 7.
Therefore, Amanda would have to work 7 hours to make $133.
