The scatter plot shows the number of DVDs Aaron sold in different months:
netineya [11]
We'll say that months = n. 

Make a set of the DVD's sold:

{20, 50, 80, 110, 140...}

In month 1, Aaron sold 20 DVDs. There is no data for month 0.

There is a constant increase of 30 DVDs every month. We can make an equation out of this to fit this data set:

a = 30n - 10

a represents the DVDs made.

We need to subtract 10 in this equation, as the starting point is 20, and the increase of 30 is different from the increase from n = 0 to n = 1.

We are looking for the amount of DVDs Aaron sold on the 13th month. Plug 13 into the equation:

n = 13
30(13) - 10 = 390 - 10 = 380

The predicted number of DVDs Aaron will sell on the 13th month is 380.

Three-quarters of a number is 15<br> work out four-fifths of the number
Anna11 [10]

Let the number be X

3/4 of X = 15


Multiplying out gives;

3X = 4x15

3X= 60

X = 20


Therefore, 4/5 of 20


Putting X = 20 we have;


4/5 x 20 = 16

Hope this help!
