The recommended time to take a math test is 23 minutes. you complete it in 18 minutes. what is the percent change between your time and the recommended time?

This is a percentage decrease, since the number gets smaller. To calculate percentage decrease, you use the formula ((y1 - y2) / y1) * 100. y1 = 23, y2 = 18. Plug in the values and solve. ((23 - 18) / 23) * 100. (5/23) * 100. (0.2174) * 100 21.74 So your answer is 21.74%
