Answer:
see explanation
Step-by-step explanation:
The exponential function is of the form
y = a
Substitute the given points into the equation to find a and b
Using (0, 4), then
4 = a ⇒ a = 4
Using (1, 24), then
24 = 4 ⇒ b = 6
Exponential function is
y = 4 ×
90 - 53.45 = 36.55
36.55 / 7.31 = 5 pounds of coffee
Answer:0.125 or 1/8
