Question 1054173: Internet Services A computer online service charges one hourly price for regular use but a higher hourly rate for designated "premium" areas. One customer was charged $25.70 after spending 2 h in premium areas and 5 regular hours; another spent 4 h in premium areas and 7 regular hours and was charged $42.70.
What does the online service charge per hour for regular and premium services?

the online service charge/hr per hour:
regular (x)
premium services (y)
5x+ 2y = 25.70
7x + 4y = 42.70
|
-10x -4y = -2*25.70
7x + 4y = 42.70
-3x = -8.7
x = $2.90 regular hrs charge
y = (25.70- 5(2.90))/2
