To find out how much Keith would earn in 9 hours, we can set up a proportion:

$45.00 is to 2 hours as x is to 9 hours.

This can be written as:

45/2 = x/9

To solve for x, we can cross-multiply:

2x = 45 * 9
2x = 405

Divide both sides by 2:

x = 405/2
x = 202.50

Therefore, Keith would earn $202.50 in 9 hours.
