The table has 3 columns, and 6 rows.

*Inventory values are determined at the end of each month.

​

For which of the six businesses shown was the percent change in value of inventory from April to June greatest?

• G
• K
• M
• R
• V

I know the answer is A, but I'm not sure how they got it. I keep getting C for my answer.

I know that you can eliminate answer choices B, D, and E because the have a decrease. But I am getting a 12% change for Business M and a 8% change for Business G. Showing that Choice C would be the answer and it is not. Please explain

If we have an increase of 6% followed by an increase of 8% the original gets multiplied by 1.06 and then by 1.08. So gets multiplied by 1.1448 which is an increase of 14.48%. Now see what you get for an increase of 2% followed by increase of 12%
