To find the price before the tip, you can use the equation: \( b + 0.15b = 29.90 \). This simplifies to \( 1.15b = 29.90 \). Dividing both sides by 1.15 gives \( b = \frac{29.90}{1.15} \approx 26.00 \). So, the price before tip is around \( \$26.00 \). Next time you're calculating tips, remember that knowing the total bill—including tips—can really help you make quick adjustments. If you find yourself often computing different percentages, consider keeping a calculator app handy or even making a simple chart as a reference!
