Answer: Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50
Explanation:
Since Sara asked 100 of the students for their favorite lunch but there are 500 students in a school, this means that the items listed will have to be multiplied by 5 (500/100) in order to get the number of students in the whole school that'll need the items listed. This will therefore be:
Pizza = 45 × 5 = 225
Burritos = 15 × 5 = 75
Hamburgers = 30 × 5 = 150
Hot dogs = 10 × 5 = 50
The correct option is A:
Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50
