By rewriting the equation from step 1 substituting the value of k into it, the value of x is 22.5
A direct variation is a type of variation that has two types of variables in which a variable can be expressed in terms of the other with its constant.
For example;
If x varies directly as y
<h3>Step 1:</h3>
Then
- x
y - x = ky ; where k is constant
<h3>Step 2:</h3>
The original question says:
- if x varies directly as y, and x = 9 when y = 6, find x when y = 15
∴
x = ky
9 = k × (6)
k = 9/6
k = 1.5
<h3>Step 3:</h3>
Now, we can rewrite the equation from step 1 substituting the value of k into it:
∴
x = ky
The value of (x) will be:
x = 1.5 (15)
x = 22.5

The matching of the demand as relatively elastic or relatively inelastic can be done as;
- Klaus' demand for orange juice (Relatively elastic)
- Amanda's annual demand for coffee(Relatively elastic)
- Jackson's demand for mystery novels(Relatively inelastic)
- Hermy's demand for Minute Maid orange juice(Relatively inelastic)
- Olivia's daily demand for Starbucks latte(Relatively inelastic)
- Stephen spends a very little part of his income on soda(Relatively elastic)
- Xavier's demand for his economics textbook(Relatively inelastic)
<h3>What is Elasticity of demand?</h3>
Elasticity of demand can be regarded as the variation on the concept of demand.
It should be noted that elastic demand involves change in quantity demanded as a result of change in price.

Jazz and blues are both characterized by the use of “blue” notes, swung notes, and syncopated rhythms. When blues musicians begin heavily improvising, the line between blues and jazz begins to diminish. In fact, mastery of blues style playing is considered part of learning to play jazz.
