The function for the cost of materials to make a muffin is f(x)=3/4x+3 where x is the number of muffin the function for the selling price of those muffins is g(f(x)) where g(x)=3x+4 find the selling price of 20 muffins

Step-by-step explanation:

The cost of materials to make a muffin is

Their selling price is determined by , where

So, to find the selling price of 20 muffin, we just have to introduce x=20 in the first function, and its results introduce it in the second function, because expresses that the first function must be introduce in the second function.

Then,

Therefore, the selling price of those muffind is $58.

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
