Answer:
n = log(
)
Step-by-step explanation:
Take the logarithm of both sides of the equation to remove the variable from the exponent.
Mathematically, when you calculate the inverse function (f-1(x)), you’re switching the “inputs” (x) and the “outputs” (f(x)) and then re-solving the equation. So, you’d start with something like:
x = 3*f-1(x) + 3
x - 3 = 3*f-1(x)
(x - 3)/3 = f-1(x)
Your inverse formula would be (x - 3)/3. Hope this helps! (Hopefully Brainly doesn’t mess up the text format.)

Answer: 12n + 25
Step-by-step explanation:
Let x represent the amount that the school pays for ordering one shirt.
This includes the $25 flat-rate shipping cost. This means that if n shirts are ordered, the total cost including shipping would be expressed as
nx + 25
The school pays $1825 for 150 shirts. The expression would be
150x + 25 = 1825
150x = 1825 - 25
150x = 1800
x = 1800/150
x = $12
Therefore, the equation that models the total cost as a function of the number of n T-shirts ordered is
12n + 25
Total purchase = (unit cost)(# of pounds purchased)
Here, that total is ($0.98/lb)(3.5 lb) = $3.43 (answer)
