Question

Tanisha is planning a backyard party. She will serve hamburgers, potato salad, strawberry shortcake, and lemonade. Including Tanisha, 28 people will be at the party. Use this information to help Tanisha plan her party. Tanisha expects that each person will drink two 8−ounce glasses of lemonade at the party, and makes 448 ounces of lemonade. Tanisha's mother buys 38 lemons. They know it takes 8 lemons to make 80 ounces of lemonade. Does Tanisha need more lemons?

Answer 1

For this case we can make the following rule of three:
8 lemons --------> 80 ounces of lemonade
38 lemons ------> x
Clearing x we have:
x = (38/8) * (80)
x = 380 ounces
We observed that:
380 <448
Therefore, more lemons are needed.
Answer:
Yes, Tanisha needs more lemons
