Answer:
3r + 2b = 600 ---(1)
r + b = 225 ---(2)
We can solve this system of equations using substitution or elimination method.
Using substitution method, we can solve equation (2) for "r" in terms of "b":
r = 225 - b
Substituting this expression for "r" into equation (1), we get:
3(225 - b) + 2b = 600
Simplifying and solving for "b", we get:
675 - 3b + 2b = 600
-b = -75
b = $75
Therefore, the cost of one bag is $75.
