solve the following word problem. then look at the work. try to determine where the mistake was made. a restaurant had to throw away 25% of a recent milk delivery because it was left out too long before it was refrigerated. the most recent delivery contained 24 gallons of milk that cost the company $3.16 each. emilio reports that the error cost the company $75.84. what error is present in emilios calculation? a) the incorrect operation is performed. b) operations are performed in an incorrect order. c) the work is incomplete and missing a step. d) a percentage is converted incorrectly.

Answer

Explanation:

Step1: Calculate the amount of milk thrown - away

The amount of milk in the delivery is 24 gallons and 25% is thrown - away. The amount of milk thrown away is $24\times0.25 = 6$ gallons.

Step2: Calculate the cost of the thrown - away milk

Each gallon costs $3.16, so the cost of the 6 gallons of thrown - away milk is $6\times3.16=18.96$ dollars.

Step3: Analyze Emilio's result

Emilio reports the error cost as $75.84$. If we assume he did $24\times3.16 = 75.84$, he calculated the cost of the entire delivery instead of the cost of the 25% that was thrown away. He performed the incorrect operation (he should have multiplied the cost per gallon by the amount of milk thrown away, not the total amount of milk in the delivery).

Answer:

A. The incorrect operation is performed.
