Final answer:
The maximum savings per gallon, based on Sudsy Wudsy's given price range, would be $1.20. However, this saving is not reflected in the provided answer choices, suggesting a discrepancy in the question or options.
Step-by-step explanation:
To determine how much money can be saved per gallon by changing suppliers from Super Suds to Sudsy Wudsy, we need to compare the per gallon cost of soap from both suppliers. However, we do not have the specific cost per gallon for Super Suds, so we should look for the larger possible savings between the various prices given for Sudsy Wudsy.
Let's compare the highest and lowest prices from Sudsy Wudsy to find the maximum potential savings per gallon. The highest is $2.20 per gallon and the lowest is $1.00 per gallon. The difference between these two prices is $2.20 - $1.00, which equals a savings of $1.20 per gallon.
Saving $1.20 per gallon on a 75-gallon order would result in total savings of 75 gallons × $1.20/gallon = $90.00 overall. Thus, answer choice (c) $2.28 is not possible given the provided price range by the supplier. Considering the given range, the highest possible savings per gallon is $1.20, which is not listed as an answer choice, so it can be assumed that there is a discrepancy in the question or options provided.
