Question

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. How much will you save PER LOAD if you buy the 15-pound box? (Round all answers to the nearest tenth of a cent.)

Answer 1

Hi @27rkryemadhi !

For your problem, we are looking for the Dollars per Load amounts. In order to do this, for each box we want to do: ` amount of dollars ` divided by ` number of loads `

For the 5 pound box, it can wash 20 loads and costs $3.50
3.50 divided by 20 = 0.175 dollars per load

For the 15 pound box, it can wash 60 loads and costs $10.00
10 divided by 60 = 0.166 dollars per load

You can subtract the two (dollars per load) values that I have calculated for you above to get your answer.
