Question

Malik
bought two tires for $45 and later sold for $65

Answer 1

Alright. We don't have the question, but Im going to assume it.

2 tires = $45

Later Sold for $65

Revenue is $20

If you mean sold both for each -

Revenue is $85

Answer 2

For this case we can indicate the profits obtained by Malik.

`P = p-c`

Where:

P: They are the profits

p: It is the sale price

c: It's the cost

We have Malik buy the tires at $ 45, then the cost is $ 45. As he sold them at $ 65 then the sale price is $ 65.

We have:

`P = 65-45\\P = 20`

So, Malik made a profit of $ 20 $

Answer:

Malik made a profit of $ 20
