Question

QUESTION 2 of 10: You have a budget of $3,000 to spend on a survey. If the base cost of the survey is $850 plus $4.50 per person surveyed,

what is the sample size you can afford?
a) 477
b) 500

Answer 1

A)477

Explanation:

Subtract 850 from 3,000

2150

Divide 2150 by 4.50 to find out how many people can be surveyed.

Answer 2

Option A.

Explanation:

Base cost of the survey is defined by the expression

Base cost C = 850 + 4.5x

where x = number of persons surveyed

If the budget to spend on a survey is = $3000

Then Number of person we can survey can be determined by

3000 = 850 + 4.5x

4.5x = 3000 - 850

4.5x = 2150

x =
`(2150)/(4.5)`

x = 477.78

But the number of persons surveyed can not be in fraction.

Therefore, sample size we can afford is 477.

Option A. is the answer.
