Question

estimate the amount of the tip by rounding the bill to the nearest dollar before calculating. 15% tip on a bill of $29.46 the amount of the tip is approximately $\square$.

Explanation:

4.5

Step1: Round bill to nearest dollar

$29.46 \approx 29$

Step2: Calculate 15% of rounded bill

$29 \times 0.15 = 4.35 \approx 4.5$ (or directly $30 \times 0.15 = 4.5$ if rounding $29.46$ to $30$ is considered, but $29 \times 0.15 = 4.35$ which is approximately 4.5)
