Answer:
x=25.61
Step-by-step explanation:
To determine the smallest amount, in dollars , that you can charge and make a profit of atleast $415, you need to find the value of x that gives p=415.
Substitute p=415 in the given quadratic equation and solve it for x.
on solving we get
The smallest amount you could charge and make a profit of $415 is $25.61

Answer:
C. 3
Step-by-step explanation:
The constant of proportionality is the slope (or rate of change) of the graph.
To find the equation of the graph;
Take points (1,3) and (3,9)
The slope (m) = change in y ÷ change in x
m =
Taking another point (x,y) on the graph;
m =
y - 3 = 3x - 3
y = 3x + 0
y = 3x
This can be expressed as;
y ∝ 3x
Which means that as y rises, x rises too but 3 remains the same. The value 3 is the constant of proportionality in this relationship.
