Answer

Explanation:

Step1: Calculate the percentage - change in teddy - bear sales

The number of teddy - bears sold in September is 346, and in October is 308. The formula for percentage change is $\frac{\text{New Value}-\text{Old Value}}{\text{Old Value}}\times100%$. $\frac{308 - 346}{346}\times100%=\frac{- 38}{346}\times100%\approx - 11%$, so statement I is incorrect.

Step2: Calculate the change in rabbit sales and total toy sales

Sales of rabbits in September is 297, and in October is 260. Change in rabbit sales is $260 - 297=-37$. Total sales in September: $346 + 297+199 + 245+225=1312$. Total sales in October: $308 + 260+285 + 186+275 = 1314$. Change in total toy sales is $1314 - 1312 = 2$. So statement II is incorrect.

Step3: Calculate the percentage - change in horse sales

Sales of horses in September is 245, and in October is 186. The percentage change is $\frac{186 - 245}{245}\times100%=\frac{- 59}{245}\times100%\approx - 24.1%$. So statement III is correct.

d. III only
