A box of Brand A laundry detergent washes 20 loads of laundry and costs $6. A box of Brand B laundry detergent washes 15 loads of laundry and costs $5.

Question

In the ratio tables that follow, fill in equivalent rates of loads washed per dollar. Include some examples where the number of loads washed is less than 15 and the cost is less than $5. Explain your reasoning.

Brand A is 20 loads on the top and it costs $6 so $6 is on the bottom underneath 20 loads.
Brand B is 15 loads on the top and it costs $5 so $5 is on the bottom underneath 15 loads.

Answer 1

I don't know what your table looks like, but an example is: plan B, 3 loads would cost $1.

Answer 2

For plan A, I have 20 loads that costs $6 and I need to figure out how I would get to the next loads. Example, 3.33 loads coasts $1 and I want to keep going and what I need to do to get to the next load.
