I need to add \$1.07 for the tip.

• You have \$20, but you haven't told us how much the bill is. There is no way to compute a tip.

BTW, a tip below 10% (and some would say 15%) would be taken as an insult to the server. If you're going to insult your server, why do you care if it's 5% or 5.37%?

• Multiply .0537 by 20.

• To figure it out, you'd need to multiply the bill's amount by the percent tip you want to leave. After you've done the multiplication, you'd get your tip amount. But first you need to convert that percentage figure into a decimal. So to convert a percent to a decimal, you'd divide the percent number it by ______. That would move your decimal point ___ places to the ______.

FYI, some of the others who've posted answers to your question gave you how much total you'd end up paying. So the amount of the bill 𝐩𝐥𝐮𝐬 the tip. And several presumed the amount of the bill itself is \$20. With the way your question is actually worded, it doesn't sound that way.

If \$20 is the total amount you have to spend, that's not necessarily the amount of the bill. So the bill could be \$11. Or it could be \$8.50. The point is the bill amount may actually be unknown. And if that's the case, which is what it sounds like to me, then you can still calculate the tip and total you'll end up paying. But it will use algebra because you'll have variables. Either way, the steps to getting the right answers are the same!

• Yes, if you were spending the entire \$20, which includes both the bill and tip amounts added together, you'd divide the \$20 amount to spend by ( 1 + % tip ). That's because the \$20 total would include the bill's amount and the tip, which is calculated off the bill's amount.

• multiply 5.37 times 2 and then divide by 100 and multiply by 10. round answer. 1.07

• or .537 x 2, to bypass your other steps (except the rounding part)

• lol.  5.37% is not mandatory. So just leave a dollar. {They probably overcharged you anyway. No math skills - get taken advantage of.}

• "Percent" are 1/100th.

So percent are directly equivalent to cents on the dollar or pence on the pound.

Add \$0.0537 (5.37 cents) to each dollar:

\$10 would be \$0.537, double that for \$20 = \$1.074

To the nearest cent, \$1.07

Adding that to \$20 = \$21.07

Working with values other than money, you can still use the same methods, it's just numbers after all, regardless of them representing dollars, metres or joules etc.

• the tip you give will be \$1.07. a percent of a number is a portion of it, like a part. for example, 5.37 percent of 100 is 5.37
