Question
Write an equation for this relationship.
- y = 18x
- y = 18.50x
- y = 22.50x
- y = 22x
Hint:
When one variable increases in increasing the other variable, then they are in direct variation.
The correct answer is: y = 18.50x
Y=kx
Equation is total cost divided by days.
y = 18.50x.
Hence, the correct option is C.
The ratio of the variables is constant for a direct variation.
