Your school band needs to buy new percussion equipment. The equipment will cost $2000. You have collected $800 in donations and previous fundraisers. If you sell sandwiches at $4 each, how many sandwiches will you need to raise the remaining funds?

300 sandwiches

Step-by-step explanation:

set it up as an equation

2000=800 + 4x

1200=4x

300=x

so you would need to sell 300 sammiches

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
