To calculate the percentage change, we use the formula:

[(New value – Old value) / Old value] x 100

From the table, the number of SARS cases reported on April 5 was 2927 and on April 10 it was 3466.

Using the formula, we get:

[(3466 – 2927) / 2927] x 100 = 18.4%

Therefore, the percentage change from April 5 to April 10 was 18.4%.

However, none of the answer choices matches this result. The closest answer is 15%, which is choice C. This could be due to rounding.
