Step-by-step explanation:
The question is asking for the percentage of pizzas left after Cesar gave 14 boxes of pizza to his classmates.
To find the percentage of pizzas left, we need to know the total number of pizzas.
Let's say Cesar had 100 boxes of pizza initially. After giving away 14 boxes, he would have 100 - 14 = 86 boxes of pizza left.
To calculate the percentage, we divide the number of boxes of pizza left (86) by the initial number of boxes of pizza (100) and multiply by 100:
Percentage of pizzas left = (86 / 100) * 100 = 86%
