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

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!
