Answer:
$90
Explanation:
$30 is the cost. 200 is the percent of Mark-up, so you take 100 percent of 30 and add it together then you get 60. Repeat that step for a total of 90. 100 percent of 30 is 30. So 30+ 30+ 30 = 90.
Cost of ticket: $30
Markup number: 200
100% of 30 is 30.
And now, 30 * 3 = 90 ($90, or 90 dollars)
