Krys bought x boxes of pastries to bring to a party. each box contains 12 pastries. she decides to keep two boxes for herself. she brings 60 pastries to the party. which equation can be used to find the number of boxes, x, krys bought? a. 2x − 12 = 60 b. 12x − 2 = 60 c. 12x − 24 = 60 d. 24 − 12x = 60

c. 12x − 24 = 60

Step-by-step explanation:

x is the number of boxes Krys bought.

12x is the number of pastries in those boxes. 2·12 = 24 is the number of pastries in the boxes Krys kept for herself. Then the number of pastries Krys brought to the party is

... 12x -24

We are told that number is 60, so we can use this equation to find x:

... 12x -24 = 60

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
