Keith earns $45.00 in 2 hours how much would he earn in 9 hours

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

45/2 = x/9

Cross-multiplying:
2x = 45 * 9

Simplifying:
2x = 405

Dividing both sides by 2:
x = 405/2

x ≈ 202.50

Therefore, Keith would earn approximately $202.50 in 9 hours.
