Answer:
Step-by-step explanation:
This is definitely exponential growth. The ruling formula will have the form
y = c·(2)^(nx), where the "2" comes from "double," c is the initial value and n is the growth constant.
Given
Cost = C = 15.82
Profit = P = 6.18
Sold 1 glass 0.50
Number of glasses sold = x
Equation
P = x*0.5 - C
Solve
6.18 = x*0.5 - 15.82 Add 15.82 to both sides
6.18 + 15.82 = 0.5x
22 = 0.5x Divide by 0.5
22/0.5 = x
x = 44
He sold 44 glasses of Lemonade to make 6.18 profit.
Rearrange them to slope-intercept form
y = 7x + 2
y = -(1/7) x + 8
product of their slopes is 7 * -1/7 = -1 so they are perpendicular
Answer:
The answer is 80, you multiply the numbers together to get volume.
