To find out how much Keith would earn in 9 hours, we can use the concept of proportions.
We know that Keith earns $45.00 in 2 hours. Now, let's set up a proportion:
$45.00 / 2 hours = X / 9 hours
To solve for X (the amount Keith would earn in 9 hours), we can cross multiply:
2 hours * X = $45.00 * 9 hours
2X = $405.00
Dividing both sides by 2:
X = $202.50
Therefore, Keith would earn $202.50 in 9 hours.
