Answer. Option B. 0.8 cents.
Solution:
With a 5-pound box of detergent will wash 20 loads of laundry, then with a 15-pound box (5*3) of detergent will wash 20*3=60 loads of laundry, and you would pay $10.00.
To wash 60 loads of laundry with 5-pound box, you would need three 5-pound box, and you would pay $3.50*3=$10.50.
Then you would save in total $10.50-$10.00=$0.50
And per load, you would save: $0.50/60=$0.008=0.008*100 cents=0.8 cents
