Final answer:
To find the percentage of chocolate cupcakes, divide the number of chocolate cupcakes (175) by the total number of cupcakes (199) and multiply by 100. The calculation yields approximately 87.94%, which is closest to option A) 87%.
Step-by-step explanation:
The question asks us to find what percentage of the cupcakes sold at a bakery were chocolate. To calculate this, we divide the number of chocolate cupcakes by the total number of cupcakes and multiply the result by 100 to get a percentage.
Total number of cupcakes = Number of chocolate cupcakes + Number of vanilla cupcakes = 175 + 24 = 199 cupcakes.
Next, we calculate the percentage as follows:
Percentage of chocolate cupcakes = (Number of chocolate cupcakes ÷ Total number of cupcakes) × 100
= (175 ÷ 199) × 100
= 0.8794 × 100
≈ 87.94%
Therefore, the answer is approximately 87.94%, which is closest to option A) 87%.
