Catherine works a hourly rate of $22.50 and earns double when she works overtime she works 40 regular hours and 12 hours overtime her is her straight time pay?

So it starts by 22.50 regularly so she worked 40 regular hours so $22.50 * 40h= $900 and in over time she gets double for working over time so $22.50 * 2 = $45 and she worked 12 hours so 12h * $45 = $540 then we need to add those two numbers up 900 + $540 = $1,440 is our answer/outcome.

The answer is 225 miles per 4.5 hours. hope this ; )
