Mr. finch buys a pack of ground coffee. he uses the same amount of ground coffee for each cup of coffee he brews. the equation below describes the relationship between the number of cups brewed (x) and the ounces of coffee (y) remaining in the pack.

how much ground coffee, in ounces, was in the full pack?

a: 3
b: 6
c: 15
d: 18

I think it was C:15 but I am not exactly sure

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
