Question

Mrs. Tandy paid a $50 registration fee to join Fitness Club. She pays a monthly rate of $25. Write an equation to represent the total Mrs. Tandy pays for Fitness Club for x months. Determine if the equation you wrote represents a proportional relationship or non proportional relationship. Explain your reasoning.

Answer 1

y=25x+50

non proportional relationship

Explanation:

The relationship is not proportional because as you go along in the function and divide y by x, the ratios do not equal each other. In order for it to be a proportional relationship the y/x ratio must be equivalent throughout the function.
