<span>First calculate the amount of overhead expenses. The selling price was $240. To find 20% of 240, multiply 240 by 0.20, which equals 48. From that, we found that the overhead expenses were $48.
To find the rate of profit, take the selling price and subtract all expenses. We know that Mr Lippman's selling price was $240, he spent $160 to buy the dryer, and he had $48 worth of overhead expenses. 240 - 160 - 48 = 32.
Therefore, the profit was $32.
To find the rate of profit, divide the profit by the total expenses. 32 / (240 + 160) = 0.08.
Therefore, the rate of profit was 8%.</span>

An exponential decay function, and use it to approximate the population in 2027 is P(t) = 4001e^-(0.0037)(28) = P(t) = 4001e^-0.1036
<h3>Exponential equation</h3>
The standard exponential function is expressed as:
P(t) = P0e^-rt
- P0 is the initial population = 4001
- r is the rate. = 0.37% = 0.0037
- t is the time
Substitute
P(t) = 4001e^-(0.0037)t
If t = 28 (by 2027)
An exponential decay function, and use it to approximate the population in 2027 is P(t) = 4001e^-(0.0037)(28) = P(t) = 4001e^-0.1036

Graph :
slope (rate of change) = (-2 - (-4) / (-2 - (-6) = 2/4 = 1/2
y int = (0,-1)
x int = (2,0)
f(x) = 2x - 2
slope(rate of change) = 2
y int = (0,-2)
x int = (1,0)
greater rate of change : f(x) = 2x - 2.....greater by 1.5
greater y int : graph....greater by 1
greater x int : graph...greater by 1
steeper graph : f(x) = 2x - 2
