A survey of North Albion students found that they favoured Avengers: EndGame to Black Panther to Mulan in a ratio of 8:7:3. If 754 students were surveyed, how many preferred each movie?

Avengers: Endgame ≈ 335

Black Panther ≈ 293

Mulan ≈ 126

Step-by-step explanation:

8+7+3=18

754/18 = 41.88888889

8*41.88888889 ≈ 335

7*41.88888889 ≈ 293

3*41.88888889 ≈ 126

335+293+126=764

y=20,x=9

When doing problems like this it is important to always note: whatever you do to one side of the = sign you have to do to the other side.

Step-by-step explanation:

For this problem it helps that they already give you what y equals to so you can plug y in the top equation to figure out what x is. See attachment for step by step process
