Question

Omar has a new credit card. He earns 300 reward points for every 100 dollars he spends. If Omar earned 1800 reward points, how much money did he spend?

Answer 1

Omar spent $600 to earn 1800 reward points.

Step-by-step explanation:

To find out how much money Omar spent, we need to use the information given. Omar earns 300 reward points for every 100 dollars he spends. So, if Omar earned 1800 reward points, we can set up the following proportion:

300/100 = 1800/x

To solve for x, we cross-multiply and divide:

300x = 100 * 1800

300x = 180000

x = 180000/300

x = 600

Therefore, Omar spent $600 to earn 1800 reward points.
