Given the statement:
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.
Determine how much will you save per load if you buy the 15-pound box.
Solution:
Find first the unit rate by dividing 3.50 with 20.
= $3.50/20
= $0.175 per load
Now we need to need to divide 10 by 60, since we all a 15-pound box contains 60 loads.
= 10/60
= $0.6 per load
Subtract the two value to determine how much is saved per load
= $0.6 per load - $0.175
=$0.425 per load
Final answer:
=$0.425 per load
