Answer:
Quantity of soap left after Juan washes 8 regular loads and 5 heavy loads of laundry [tex]=12.9[/tex] pounds.
Step-by-step explanation:
Number of scoop of soap used to wash a regular load of laundry = One 0.15 pound scoop
Number of scoops of soap used to wash heavy work clothes = Two 0.15 pound scoops
As Juan washes 8 regular loads and 5 heavy loads of laundry,
Total quantity of soap used = [tex]8(0.15)+5(2)(0.15)=1.2+1.5=2.7[/tex] pounds
As a box of laundry soap weighed 15.6 pounds,
quantity of soap left after Juan washes 8 regular loads and 5 heavy loads of laundry [tex]=15.6-2.7=12.9[/tex] pounds.
