An advertisement claims that a 5-pound box of detergent will wash 20 loads of laundry. a 5-pound box costs $3.50. a 15-pound box costs $10.00. about how much will you save per load if you buy the 15-pound box?

5 pounds = 20 loads = $3.50

Convert to per-load:

1/4 pound = 1 load = 13.5 cents

15 pounds = 60 loads = $10

Convert to per-load:

1/4 pound = 1 loads = 16.7 cents

You would save 3.2 cents per load
