4. The sale price of shrimp at a local grocery store is \$1.15 for the first ounce and \$0.95 for each additional ounce. Which function rule shows how the cost of shrimp, y, depends on the number of ounces, x?

1. 24
2. E=Mx
3. y=5+2.25x
4. y=x+.95

1. Reiny

1. how did you get 24 ?

f(x) = x^2 - 3x + 2
f(-2) = (-2)^2 - 3(-2) + 2
= 4 + 6 + 2 = 12

2. E = 12m

3. correct

4. y = 1.15 + .95(x-1)

2. Anonyous

Omg thank you so much!!
