Question

A survey was conducted to determine the food choices of the 80 students at a picnic. The types of food are in the graph belowSalad 10%Sandwich 20%Hamburger 15%Hotdog 15%Pizza 30%Based on the graph how many more students chose pizza than students who chose salad

Answer 1

First, find the amount of students who chose pizza and the amount of students who chose salad based on the total amount of students in the survey and the corresponding percentages.

Pizza: 30%

`(30)/(100)*80=24`

Then, 24 students chose pizza.

Salad: 10%

`(10)/(100)*80=8`

Then, 8 students chose salad.

Subtract the amount of students who chose salad (8) from the amount of students who chose pizza (24) to find how many more students chose pizza than students who chose salad.

`24-8=16`

Therefore, there are 16 more students who chose pizza than students who chose salad.
