Step-by-step explanation:
5n-2
5(4) - 2
20-2=18
A= 18
5n - 2 =48
5n=48+2
5n=50
divide by 5
n= 10
B=10
Divide the estimated number by the exact number and multiple by 100
The equation set up is:
0.5x² - 40x + 15300 = 0
Cost, C(x) = 35x + 300
Revenue, R(x) = 75x - 0.5x²
Profit, P(x) = 15000
Profit = Revenue - Cost
P(x) = R(x) - C(x)
15000 = 75x - 0.5x² - (35x + 300)
15000 = -0.5x² + 40x - 300
0.5x² - 40x + 15000 + 300 = 0
The quadratic equation to get the number of items sold is shown below:
0.5x² - 40x + 15300 = 0

Answer:
Scale Factor = 2.8
Step-by-step explanation:
The scale factor is how many times LARGER is the enlarged pic.
We can divide the enlarged pic (16.8) by original (6) to get the scale factor:
Scale Factor =
