The equations that you would use is 14x+6x+16x=326, where x is equal to the number of instruments sold. If you plug in the 12 sets of maracas, the 5 sets of claves and x djember drums and multiply by the prices for each instruments, you should be able to find your answer. Your answer should be you sold 8 djembe drums. Using the information i provided to you plug the numbers in and see if your answer matches up with mine. let me know if you have any further questions.

(2 x 3) = 6
12 - 6 = 6
Your answer is 6.
Answer:
After expanding the polynomial 
we get 
Step-by-step explanation:
We need to expand the polynomial
Multiply the terms:
So, after expanding the polynomial we get
Answer:y = 65x/z
Step-by-step explanation:
Suppose y varies directly with x and inversely with z. It means that as y increases or decreases, y increases or decreases while z decreases or increases respectively.
In order to remove the variation symbol and replace with an equation symbol, we would introduce a constant of variation, k. It becomes
y = kx/z
When x= 65 and z=5, then y= 26. We would substitute these value to get the constant of variation, k. It becomes
26 = 65k/5
65k = 65
k = 1
The equation of combined variation will be
y = 65x/z
67 percent is your answer
