an advertisement claims that 7 out of 8 people prefer brand x. suppose 216 people were interviewed. find the number of people wh

anzhelika [568]

Answer:

189 people

Step-by-step explanation:

We can make a proportion to solve

We know that 7 out of 8 people prefer Brand X, and p out of 216 people prefer Brand X, so

7/8=p/216

To solve, we need to get p by itself.

To do this, we must multiply both sides by 216 to "reverse" the division being done to p.

216(7/8)=(p/216)216

189=p

So, out of 216 people, 189 people will prefer Brand X.
