Question

In a survey, 200 people, or 40%, said they were on a diet. How many people were surveyed?

A) n * 200 = 40; 0.2 people

B) n * 200 = 40; 50 people

C) n * 40 = 200; 5 people

D) n * 40 = 20,000; 500 people

Answer 1

"\(\bf \text{In a survey, 200 people}\), or 40%, said they were on a diet. How many people were surveyed"

tis pretty much a given

Answer 2

40% of n people = 200 people
Because 40% equals 0.4, "of" means multiplication,
0.4 * n = 200 people
which is the same as
n * 40 = 20,000 people
if multiply both sides with 100.
Then, solve for n so that you will get
n = 500 people.
Good Luck with this!
