A bakery sells chocolate cupcakes and mocha cupcakes. One day it sold 162 chocolate and 138 mocha. What percent of the cupcakes sold that day were chocolate?

To find the percentage of chocolate cupcakes sold, we first need to find the total number of cupcakes sold that day.

Total cupcakes sold = 162 chocolate + 138 mocha
Total cupcakes sold = 300

Now, to find the percentage of chocolate cupcakes sold, we divide the number of chocolate cupcakes sold by the total cupcakes sold and multiply by 100.

Percentage of chocolate cupcakes sold = (162/300) x 100
Percentage of chocolate cupcakes sold = 0.54 x 100
Percentage of chocolate cupcakes sold = 54%

Therefore, 54% of the cupcakes sold that day were chocolate cupcakes.
