- After 1 hour passed, 2 inches of show fell
- After 5 hours passed, 10 inches of snow fell
- And so on
This means, that points (1,2), (5,10) lie on the graph. This graph passes through the origin, so its equation is
where k is the slope
Find k:
so the equation is and the slope is k = 2.

Answer:
The variable is the number of clothes sold 'x'.
The equation is:
The number of clothes sold by Lynn are 74.
Step-by-step explanation:
Let the number of pieces of clothes sold be 'x'.
Given:
Earning of Lynn per cloth is $0.25.
Fixed earning of Lynn per day is $100
Total earning after selling 'x' clothes is $118.50.
