324 people went to an exhibit the first week. On the second week, 549 people went. What was the percent increase?

First find the difference between the two weeks:

549 - 324 = 225

Now divide the difference by the first week value:

225 / 324 = 0.694 x 100 = 69.4% (round the answer as needed).

percent increase = 69.44%

Step-by-step explanation:

original quantity = 324

final quantity = 549

increased quantity = 549-324 = 225

using the formula; percent increase = Increase/original quantity * 100%

= 225/324 * 100%

=69.44%
