Two questions I'm stuck on.
Homework problem 1:
The graph below shows the price change of an item over several years. Find the rate at which the price is increasing.

Homework problem 2:
The bar graph below shows the current shelf stock of the canned vegetable section in a market. The number of cans of each vegetable is shown. How many cans of beets are on the shelf?

I want to believe it's 28, but then I thought maybe 27.

You get the the answer from (210 - 40)/(7 - 3) =170/4 = 42.5
Looks like 28 to me - it's slightly over half way between 25 and 30.

Total increase = 170 No. of years = 4 170 divided by 4 = 42.5
.2nd question is a matter of judgement and having marked GCSE exams and SATS paper the guidelines will probably say something like "27 allow for 1 either way" so full marks will be given whether you answer 26 27 or 28 .
