Step-by-step explanation:
When something is inversely proportional it can be solved by using the equation:
y = k/x
where k is the constant.
So using this we can plug in x and y to find the value of k.
27= k/3
Next we isolate k and find that k = 81. Now we use this to find the value of x when y = 9. Plug in y and you get x = 81/9 or x = 9
This is a systems of equation problem.
First, set up the equation.
814=w+d w=d-36
Second, insert w= in for w in the equation.
814=d-36+d
Third, combine like terms.
814=2d-36
Fourth, solve the equation by adding 36 and dividing by 2 to both sides.
814=2d-36
+36 +36
___________
850=2d

__________
425=d
So the dryer (d) costs $425.
