Final answer:
To find an equation for this situation, you can use the equation 85% of x = $267.75, where x represents the original price of the computer monitor. By solving this equation, you can find the original price of the monitor.
Step-by-step explanation:
To find an equation for this situation, we can start by letting 'x' represent the original price of the computer monitor. After a 15% reduction, the price of the monitor becomes 85% of the original price. Mathematically, this can be represented as:
85% of x = $267.75
To solve for 'x', we can multiply both sides of the equation by 0.85 to isolate 'x'. This gives us:
x = $267.75 / 0.85 = $315
Hence, the equation we can use is 85% of x = $267.75.
