Question

Lin opened a lemonade stand during the summer. She

Answer 1

Answer:

59 cups ;

10 cups

Step-by-step explanation:

Given that he fitted model :

c = 2t - 89

Where, c = cups of lemonade sold ; t = high temperature

On a day when high temperature is 74 degrees ; cups of lemonade sold

Hence,

c = 2t - 89

c = 2(74) - 89

c = 148 - 89

c = 59 cups

Sunday is expected to be 5 degree warmer than on Saturday :

The number of cups sold on Sunday using the fitted model should be :

Difference in temperature between Saturday and Sunday multiplied by the slope value

Slope value from the model = 2

Temperature difference = 5

Difference in Number of cups :

2 * 5 = 10 cups

Number of lemonade sold on Sunday will be 10 cups more than that sold on Saturday
