I think you just multiply the amount of pennies for one grooming job by 9
For this case we have the following functions:
When x = 0 we have: For y1:

For y2:

Therefore, we have to:
When x = 5 we have: For y2:

For y3:

Therefore, we have to:
When x = -1 we have: For y1:

For y2:

For y3:

Therefore, we have to:
Answer:
When x = 0, y1 = y2
When x = 5, y2 <y3
When x = -1, y3 <y1 <y2
Answer: D: 23.99
Step-by-step explanation:
What number is 0.01 less than 24?
The number 0.01 less than 24 is equal to 24 - 0.01;
24 - 0.01 = 23.99
D: 23.99
2 by 3.5 is the area for the model.
Every 1 is meant to represent 20, so multiply both 2 and 3.5 by 20.
2 * 20 = 40
3.5 * 20 = 70
40 * 70 = 2800 in^2
Every 12 inches is 1 foot so divide 2800 by 12^2 (one square foot), or 144.
2800/144 = 19.44444
Round down because .4 is less than half.
Approximately 19 ft^2
