Omar spent 600 dollars for earning 1800 reward points.

Explanation

Omar earns 300 reward points for every 100 dollars he spends.

Suppose, he spent
x dollar for 1800 reward points.

Now according to the ratio of "amount of money spent" and "reward points" , the equation will be......


(x)/(1800)=(100)/(300)\\ \\ 300x=180000\\ \\ x=(180000)/(300)=600

Thus, Omar spent 600 dollars for earning 1800 reward points.
