Okay so you want 10 loads, 12 quarters per load so there's 120 quarters for 10 loads, 120 quarters is the equivelant of 30 dollars so how many hours would it take at $12/hr to reach 30 dollars...you're doing 1 and 1/4 hours per shift, and so 2 shifts is 2 and 1/2 hours so what does 2 and a 1/2 hours give you...1/2 of 12 is 6, so 12+12+6 equals 30...so that's 30 dollars....so you need 2 and a half hours which is the equivelant of 2 shifts.
