Quantitative Literacy Practice Exam 2026 – Comprehensive Preparation Guide

To determine the percentage of the tip in relation to the dinner bill, you can use the formula for calculating percentage, which is:

Percentage = (Part / Whole) × 100%

In this case, the part is the tip amount of $14.36, and the whole is the total dinner bill of $76.64.

First, divide the tip by the total bill:

14.36 / 76.64 ≈ 0.1875

Next, to convert this decimal to a percentage, multiply by 100:

0.1875 × 100% = 18.75%

This value rounds to approximately 19%. Therefore, the option indicating that the percentage of the tip relative to the dinner bill is about 19% is correct.

This calculation method clearly shows how to find the percentage and explains that a tip of $14.36 on a $76.64 bill amounts to nearly 19% of the total.
