There is a few ways to do this but I am going to use the variation equation.

Variation Equation:
y = kx
First we need to find k, which is the constant of variation
5 = k50
5/50 = k
1/10 = k
k= 1/10

Now that we have found the constant of variation, we can find how much the spring will stretch with 170 pounds.
y = kx
y = (1/10) times 170 = 17 inches

The ratio of M & M’s to raisins in a bag of trail mix is 3:5. If there are 36 M & M’s, how many raisins are there?
Iteru [2.4K]
The correct answer is 60 raisins.  To get this answer you will write a proportion of M & Ms to raisins and create and equivalent ratio using the number 36.  

After you have the proportion set up, you will use cross products to solve for the number of raisins.

You can also use equivalent ratios to find the number of raisins.  

Both of these strategies are shown in the attached picture.
