You are selling candy bars for a fundraiser. you want to sell at least $200. If snickers cost $2 per bar and M&M's cost $3 per bag, then write an inequality that represents all the possible combinations you can sell to meet your goal.

Step-by-step explanation:

Goal = > $2500

Amount raised = $700

Amount needed to raise = $2500 - 700 = $1800

Number of candy bars needed = x

Price of a candy bar = $1.50

1.5x > 1800

x > 1800 ÷ 1.5

x > 1200

They need to sell more than 1200 candy bars.

- 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

ok
