What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

First, let's find the cost of the meal before tax and tip.

We know that the total bill, including tax, is $55.35, which is equal to 100% + 8% (the tax rate) = 108% of the original meal cost.

We can set up an equation to solve for the original meal cost (let's call it x):

x + 0.08x = 55.35

Simplifying the left-hand side:

1.08x = 55.35

Dividing both sides by 1.08:

x = 51.25

So the cost of the meal before tax and tip was $51.25.

Next, let's calculate the amount of tax they paid:

0.08x = 0.08(51.25) = 4.10

So the tax they paid was $4.10.

Now let's calculate the tip they left for the server. They left a 15% tip on the original meal cost of $51.25:

0.15(51.25) = 7.69

So the tip they left was $7.69.

Finally, to find out how much they spent in total, we add up the cost of the meal, the tax, and the tip:

51.25 + 4.10 + 7.69 = 63.04

Therefore, the Keller family spent a total of $63.04.
