5. on friday, 280 knox middle school students purchase pizza in the cafeteria. thirty - nine percent purchased pepperoni pizza, 26% purchased sausage, and the rest purchased cheese pizza. how many students bought cheese pizza?
Answer
Explanation:
Step1: Find the percentage of cheese pizza buyers
First, we know that the total percentage of all pizza buyers is (100%). The percentage of pepperoni pizza buyers is (39%) and sausage is (26%). So the percentage of cheese pizza buyers is (100% - 39% - 26% = 35%).
Step2: Calculate the number of cheese pizza buyers
We know the total number of students is (280). To find (35%) of (280), we convert the percentage to a decimal ((35% = 0.35)) and multiply by (280). So the calculation is (280\times0.35). [ 280\times0.35 = 98 ]
Answer:
98
