Question

omar has a new debit card. he earns 1,800 reward points for spending 300 dollars.

dollars

Explanation:

Step1: Find points per dollar

First, find how many reward points per dollar. The rate is \( \frac{1800 \text{ points}}{300 \text{ dollars}} = 6 \text{ points per dollar} \).

Step2: Calculate spending for 600 points

Let \( x \) be the spending. We know \( 6 \text{ points/dollar} \times x = 600 \text{ points} \). Solve for \( x \): \( x = \frac{600}{6} = 100 \) dollars.

Answer:

100
