Answer:
Step-by-step explanation:
A.)
Let the equal number of hours be represented by variable h;
The two equations will be as follows;
Jack; 40 +30h
Mark; 50 +25h
Next, equate them;
40 + 30h= 50 + 25h
30h - 25h = 50 - 40
5h = 10
h =10/5
h = 2
Therefore, they charge the same amount at 2 hrs.
B.) The amount charged;
Replace the variable H in any of the two equations above with 2 to solve for the amount.
Equation 40+30h = 40 + (30*2)
=40 + 60
= $100
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
i think it is A hope it hleped
