David works in a store and he gets pay for $7.25 per hour. he will get double pay if he works more than 50 hours weekly, and on and half pay if he works over than 40 hours weekly. how much should david get pay if he worked 62.4 hours last week? what would be the actual amount that david received if the tax rate was 12%?

62.4 hours = 40 hours (regular rate) + 10 hours (one and half time rate)  + 12.4 hours (double rate)

Regular Rate for 40 hours = $7.25 x 40 = $290

One-and-half time Rate for 10 hours = $7.25 x 1.5 x 10 = $108.75

Double Pay Rate for 12.4 hours = 7.25 x 2 x 12.4 = $179.80

Total Pay = $290 + $108.75 + $179.80 = $578.55

Tax = 12% x $578.55 = 0.12 x 578.55 = $69.43

Amount received = $578.55 - $69.43 = $509.12

$509.12
