To Explain:The real world quantities that have a proportional relationships

Answer to Problem 18HP
(a) Relationship between number of gallons of fuel we put in the car and the amount of money we pay.
(b) If you get paid ten dollars an hour, there is a linear relationship between hours and pay.
Explanation of Solution
Given:Write about two real world quantities that have a proportional relationships. Describe how you could change the situation to make the relationship between the quantities non proportional.
Real world quantities for linear proportional relationship
(a) Relationship between number of gallons of fuel we put in the car and the amount of money we pay.
(b) If you get paid ten dollars an hour, there is a linear relationship between hours and pay.
By changing the values non linear
So that the ratios are not equal
Then
The relationship becomes non proportional.
