Different collections in total? Or like pairs of 2 how many?
The point-slope form:

We have m = 56 and the point (-8, -4). Substitute:

100 dollars should be a one time fee so that has to be added to the equation, and since it is a one time fee it should not have a variable next to it.
It also says that you have to pay 720 dollars per month, so it has to have a variable next to it to show the number of months that she needs to pay that amount of money.
The answer should be D.
y= 720x +100
The answer is 52% because there is a total of 25 marbles and if you add the red and blue marbles you get 14 which is more than the green mables which is more than half the amount of the total marbles
