He earned 1800 reward points for 600 dollars

Explanation:

Given the statement: Omar has a new credit card. He earns 300 reward points for every 100 dollars he spends. If Omar earned 1800 reward points.

Unit rate are expressed as a quantity of 1, such as 3 feet per second or 4 miles per hour, they are called unit rates.

Earn 300 reward point for every 100 dollars.

⇒ unit rate per reward =
`(100)/(300)` dollars

we have to find how many dollars he earned for 1800 points.
