Answer:

Rates :

$95 per hour and $105 per hour

Step-by-step explanation:

Let their rate = x and y respectively :

10x + 15y = 2475 - - - - (1)

x + y = 200 - - - - (2)

x = 200 - y - - (3)

Put (3) into (1)

10(200 - y) + 15y = 2475

2000 - 10y + 15y = 2475

5y = 2475 - 2000

5y = 475

y = 95

x = 200 - y

x = 200 - 95

x = 105
