To solve for the true hourly wage simply add the 2 rates together.
20 dollars/500 hours = 2/50 = 0.04 dollars per hour.
The true rate would be $18.000 + $0.04 = $18.04 per hour.
63% decrease.
0.63•80=50.4kg
80kg-50.4kg=29.6kg
Each roast is 7.9 lbs so you multiply that by 3.
7.9x3=23.7
now add 1.4
23.7+1.4=25.1
the round of beef weighed 25.1 pounds
