Question

A customer paid a total bill of $23 at a restaurant. Of that amount, $20 was the cost of the metal and the rest was the tip. Circle all of the equations that can be used to find what percent the tip is of the meal.

Answer 1

We conclude that 86.9% cost food.

Therefore, we conclude that 100% - 86.9% = 13.1% is the tip cost.

Explanation:

We know that the customer paid a total bill of $23 at a restaurant.

Of that amount, $20 was the cost of the meal and the rest was the tip.

We use the following proportion:

`23:100 \%=20:x\%\\\\23x=20\cdot 100\\\\23x=2000\\\\x=(2000)/(23)\\\\x=86.9\%`

We conclude that 86.9% cost food.

Therefore, we conclude that 100% - 86.9% = 13.1% is the tip cost.
