4. Nine fruit juice bottles contain 4 1/2 litres of fruit juice between them.

Answer:

2 $\frac{1}{2}$ litres or 2.5 litres

Step-by-step explanation:

From the question, 9 fruit juice bottles contain 4 $\frac{1}{2}$ litres of fruit juice. Therefore, to find how many litres of fruit juice would be contained in 5 fruit juice bottles, you multiply 5 by 4 $\frac{1}{2}$ litres and you divide the product by 9.

i.e. Let the quantity of the fruit juice for 5 bottles be x.

9 juice bottles ===> 4 $\frac{1}{2}$ litres

5 juice bottles ===> x

∴x = $\frac{5 * 4\frac{1}{2} }{9} litres$

x = $\frac{5 * 4.5}{9} litres$

x = $\frac{22.5}{9} litres$

x = 2.5 litres or 2 $\frac{1}{2}$ litres

To answer this question, you need to write a linear equation (because the graph is a visibly straight line) that models this situation, then plug in 12.

The general format for a linear equation is y=mx+b, where m is the slope and b is the y intercept. The y intercept of a line is where it crosses the y axis; for this line, it crosses the y axis at (0, 0) so the y intercept is 0.

To find the slope, use the slope equation: (y2-y1)/(x2-x1). For y1, y2, x1, and x2, just pick any two points on the line. We will use (1, 30) and (2, 60):

(60-30)/(2-1)

30/1

30

The line is y=30x.

Plug in 12 for x:

y=30(12)

y=360

3). 360
