You may solve this ratio by cross multiplying. To do this, you multiply the numbers diagonally across from each other.
x/10 = 1/5
10(1) = x(5)
10 = 5x
2 = x
Answer:
x = 2
You would have to multiply to find X
The answer is 220 at least. Here's how it goes
Multiply $205 with 6 and subtract the sum of the five years from it. That's how I think and I hope it helps
12w+15r=18.30 /*2
15w+10r=16.75 /*3
24w+30r=36.60, subtract this equation from the other one
45w+30r=50.25
21w=13.65
w=13.65/21
w=0.65 is a cost per pound for wheat flour
From the first equation we have
r=(18.30-12w)/15
r=(18.30-12*0.65)/15
r=0.70 is a cost per pound for rye flour
