Question

A movie theather sells snacks to 30% of its customers each day. On saturday, 186 customers bought snacks. How many customers went to the theather on saturday?

a. 242

b. 520

c. 558

d. 620

Answer 1

d. 620

Explanation:

Make it a ratio: 186 compared to 30 and x is the whole, just as 100 is the whole in 30% so those two are compared.

186/x = 30/100

Cross multiply

3x = 1860

Evaluate

x = 620

I know this question was like a year ago but the wrong answer was bothering me, haha. The answer is d. 620.
