Mary and Kate picked up a map of the zoo at the main entrance. The actual distance between the
entry point and the Avian Center was 23 miles. The distance on the map was 9.2 inches. Determine
the scale factor that was used to design the map.

5n = $10.25

Step-by-step explanation:

We know that the tub is 5 pounds, and costs $10.25. We also know that n is in dollars per pound. Dollars per pound can be written as the product of dollars, divided by pounds, so we can plug that in being n = $10.25/5, next we want to make the equation contain an integer on both sides and not contain any fractions, so we multiply both sides by 5, resulting in 5n = $10.25
