Question
A group of students participated in a study. It was determined that for each hour of experience performing a certain task, the time necessary for each student to complete the task decreased by 5%. Wendy took 30 minutes to complete the task with no experience. Which function models the amount of time T, in minutes, it will take Wendy to complete the task after x hours of experience?
- T = 30(0.05)x
- T = 30(0.50)x
- T = 30(0.95)x
- T = 95(0.30)x
The correct answer is: T = 30(0.95)x
Given task decreased by 5% = > 0.95
T = 30(0.95)x
