Question

How much would a 20% tip on a restaurant bill for $60.50 be, and how much would that make the total amount paid?

Answer 1

`20%` is `20/100`, which we can also express as `0.2`. If we multiply this by the bill, we get the size of the tip: `0.2 times $60.50 = $12.10`. Adding this to the bill gives `$60.50 + $12.10 = $72.60`.

Explanation:

I'm an Australian and we're more comfortable dealing with decimals. I feel like Americans are more comfortable dealing with fractions, so we could also solve this as follows:

20% is 20/100, which we can also express as 2/10 or 1/5.

If we multiply this by the bill, we get the size of the tip:

`1/5 times $60.50` = `($60.50)/5` = `$12.10`.

Adding this to the bill gives `$60.50 + $12.10 = $72.60`.
