Question

Alice made lemonade for her school's fall festival as a fundraiser. She made a total of 5 gallons, which is 80 cups. They sold, on average 16 cups per hour. Write an equation that represents y, the number of cups of lemonade remaining, after x hours

Answer 1

y = 80-16x

Explanation:

She made a total of 80 cups and sells 16 cups per hour

So in x hours she would have sold 16 * x = 16x cups

So the number of cups remaining will be;

y = 80-16x
