Hi

whenever numbers look horrible it is agood idea to see what you would do if the numbers were easier.   

so for this one you could ask yourself.  If I earn $10 for 2 hours work how much do I get per hour?

$5 because 10 divided by 2 = 5     $5 first hour +$5 second hour = $10  That works.

I took the dollars and divided by the hours. Mmmm

38.45 divided by 4.5 must give the right answer.
