Let x be the price of one donut and y be the price of one kolache. Then we have:
6x + 2y = 8.84 4x + y = 5.36
We can solve for y by multiplying the second equation by -2 and adding it to the first equation:
6x + 2y = 8.84 -8x - 2y = -10.72
-2x = -1.88
Dividing both sides by -2, we get:
x = 0.94
This means that one donut costs $0.94
