Answer:
30% tip
Step-by-step explanation:
First, we need to find out how much money Brayden left for the tip. To find this, we'll subtract the initial bill from the remaining bill. It will look like this:
$28.60 - $22 = $6.60
We now know that Brayden left a tip of $6.60. Next, we need to set up a proportion to find out what percentage that is. For the first fraction, we need to plug in the tip and the initial bill. We'll use <em>t </em>to represent the tip, and<em> w </em>to represent the whole<em>. </em>It will look like this:
Next, we need to set up the second fraction of the proportion. We know that every percent is out of 100, so we know that 100 will be our bottom number. We are solving for the percentage out of 100, so we will use <em>x </em>in its place. The final proportion will look like this:
Finally, we'll cross multiply and divide to get the final answer. First, multiply 6.60 by 100 to get 660. Finally, divide 660 by 22 to get a final answer of 30%. Brayden left a 30% tip on the bill. The final calculations are as follows:
6.60 X 100 = 660
660 / 22 = 30%
