A local family-owned plastic cup manufacturer wants to optimize their production mix in order to maximize their profit. They produce 2 sizes of plastic cups for a chain of stores selling smoothies; 16 oz and cups. Currently, the smoothie company purchases three times as many 16 cups to 20 oz cups. The profit on a case of 20 plastic cups is $20 while the profit on a case of 16 oz plastic cups is $25. The cups are manufactured with a machine called a plastic extruder which feeds on plastic resins. Each case of 20 cups requires 18 of plastic resins to produce while plastic require 14 case. The daily supply of plastic resins is limited to at most 1800 pounds. About cases of either product can be produced per hour. the moment, the family wants to limit their workday to 8

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

uhhh idk u yolo?

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
