Give an explanation with your answer! the table below shows the change in the value of shares over the last three years. calculate the percentage change in shares from the start of 2013 to the end of 2015.

First, lets convert them into multipliers:

The multiplier for a:

                             25% increase = 1.25

                             40% decrease = 0.6

                             40% increase  = 1.4

Now to work out the overall percentage change, we just times all of the multipliers together, and convert it back to a percentage:

1.25 x 0.6 x 1.4 = 1.05    

So the overall multiplier is 1.05

And a multiplier of 1.05 = a 5% increase.

That means that the percentage change is + 5%

The percentage change in shares from the start of 2013 to the end of 2015 is:

+ 5%

Note: if you haven't been taught multipliers - then ask and I'll try my best to explain!

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.

the correct answer is 5 6 and 7
