+2440 Our goal is to isolate Q. Let's solve for Q:
| \(0=20-0.05q\) | Subtract 20 on both sides of the equation |
| \(-20=-0.05q\) | Convert 0.05 into a fraction to ease calculation |
| \(-20=-\frac{1}{20}q\) | Multiply by -20 on both sides to get rid of that pesky fraction |
| \(400=q\) | You're done! |
