The Samuel family orders 2 chicken tacos, 2 nachos with chicken, 1 chip, and queso, 1 chicken fajitas, 1 beef fajitas, 1 combo platter, and 3 soft drinks the special that day is 15% off the total bill, how much is their bill including tax (6%) but not including the tip?

It probably depends on how much each item costs first. You can’t figure out the total bill or tax without the price.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
