Answer:

Redskins cost $0.25 and golden roughs cost $0.35.

Step-by-step explanation:

Let r be the cost of a redskin and g the cost of golden roughs. So we have the system of equations:

r + 4g = 1.65

2r + 3g = 1.55

Multiply the first equation by -2:

-2r - 8g = -3.30

Adding this to the second equation:

-5g = -1.75

g = 0.35.

Now substitute this into the first equation:

r + 4*0.35 = 1.65

r  = 1.65 - 1.40

r = 0.25.
