Answer:

First you have to find out how many students were asked.

Rock 20

Hip-hop 40

Country 30

Aiden asked to 90 students

Step-by-step explanation:

It’s a Rule of 3:

If in a group of 90 students 20 chose rock. In a group of 360, How many students will choose rock?

90s - 20rock

360- ?

360(20)/90 = 80

Then do the same thing with country.

90s - 30country

360s- ?

360(30)/90 = 120

The total of country and rock will be:

200 students
