Answer:
The first rate was 120
The second rate was 85
Step-by-step explanation:
r1 = x
r2 = y
10*x + 15*y = 2650
x + y = 205 Multiply this equation by 10
10x + 10y = 2050 Subtract this equation from the top equation.
10x + 15y = 2650
10x + 10y = 2050
5y = 600
y = 600/5
y = 120
x + y = 205
x + 120 = 205
x = 205 - 120
x = 85
