Answer:
Number of quarts=16
Money earned=$32
Step-by-step explanation:
Given
1 Gallon= 4 Quarts
Therefore Number of quarts
[tex]= \text{number of gallons} \times 4\\= 4 \times 4\\=16[/tex]
Therefore Number of quarts of lemonade prepared by them = 16 quarts
As they charge $2 for each quart
⇒
Total money made if they sell it all
[tex]=\text{number of quarts} \times 2\\= 16 \times 2\\=32[/tex]
Therefore, if they are to sell all the lemonade that they prepared
They would earn=$32
