The March sales of Jazz records is an illustration of proportions, and the number of jazz records sold all year is 7x
<h3>How to determine the total number of sales?</h3>
The sales in March is given as:
Proportion = 1/7
Let the actual number of sales in the month of March be x, and the total sales in the year be y.
So, we have:
1/7 * y = x
Make y the subject
y =7x
Hence, the number of jazz records sold all year is 7x

<em>Question 7:</em> Is the Graph a 1-to-1?
The answer is: No
<em>Reason: </em>If you look at the graph, you see that when the x value is -1 the y value is -2, when x is 0, y is 0. When x is 1, y is 2, when x is 3, y is 4, and so on and so on...
<em>Question 9:</em> What is f(2)?
The answer is: When f (or x) is 2, y is 3... so f(2) = 3
<em>Reason:</em> (Look at reason for Question 7)
