Answer 1

Step-by-step explanation

If a person uses Redbox then we have the following cases:

- A: the person uses only Redbox

- B: the person uses only Redbox and Netflix

- C: the person uses only Redbox and a video store.

- D: the person uses Redbox, Netflix and a video store.

There are 52 people in case A, 44 people in case B, 19 people in case C and 15 in case D. Then the total amount of people that use Redbox is given by the sum of all these numbers:

`52+44+19+15=130`Answer

Then the answer is 130 people.
