Final answer:
The percent increase for the Pet Store is approximately 156%.
Step-by-step explanation:
To calculate the percent increase, we need to find the difference between the new sales and the original sales, and then divide that difference by the original sales.
Step 1: Calculate the difference. $29,184 - $11,400 = $17,784.
Step 2: Divide the difference by the original sales. $17,784 / $11,400 ≈ 1.56.
Step 3: Multiply by 100 to convert the decimal to a percentage. 1.56 × 100 ≈ 156%.
Therefore, the percent increase for the Pet Store is approximately 156%.
