Answer:
If A varies directly as B and inversely as C, we can write the relationship as A = k * (B/C), where k is the constant of variation.
Given that B = 4, C = 2, and A = 10, we can substitute these values into the equation to find the value of k:
10 = k * (4/2)
10 = k * 2
k = 10/2
k = 5
Now that we have the value of k, we can use it to find A when B = 15 and C = 25:
A = k * (B/C)
A = 5 * (15/25)
A = 5 * 0.6
A = 3
Therefore, when B = 15 and C = 25, A is equal to 3.
