Answer:
21.1%
Step-by-step explanation:
(25 - 24.3) / 1.2 = 0.5833 z score = 78.9%
You need the percent that spend more than 25 hrs per week, so 100 - 78.9 = 21.1%

solve for "k", to find "k" or "constant of variation"
Okay so I got $742.50
This is what I did :
(1- .10) (825)
= 0.9 (825)
Which gives me $742.59
