the table shows the number of candies packed by machine c. the equation shows the number of candies packed by machine d. in both representations, x is a measure of the number of minutes and y is a measure of the number of candies packed.

machine c candy packing
x (minutes) y (candies)
2 150
4 300
6 450
8 600

machine d: y = 130x

how many more candies could machine d pack than machine c in 11 minutes?

a. 65
b. 130
c. 450
d. 605

First, we're going to see the candies per minute that machine C packs.
150 / 2 = 75

Now that we know that machine C packs 75 candies per minute, we're going to multiply the candies machine C makes by 11 minutes.
75 x 11 = 825

We're now gonna do the same with machine D.
130 x 11 = 1430

Then we're going to find the difference between machine C and machine D, we do this because the question basically asks how much more candies can machine D pack than machine C.
1430 - 825 = 605 candies.

This is how we find our final answer.

Our answer would be D) 605.

Hope this helps!~

Y=3x+1 so the first one
