After 6 months, the total cost of Tanya’s gym membership was $200. After 8 months, the total cost was $260. Is this a proportion
ycow [4]

Answer:

Non-proportional; the rate of change is $30/month

Step-by-step explanation:

After 6 months, the total cost was $200.

After 8 months, the total cost was $260.

Find the rate of change using formula

\dfrac{f(b)-f(a)}{b-a}

Hence,

\text{Rate of change}\\ \\=\dfrac{\$260-\$200}{8-6}\\ \\=\dfrac{\$60}{2}\\ \\=\$30\ \text{per month}

At this rate, after 6 months Tanya paid

\$30\cdot 6=\$180

But after 6 months, the total cost of Tanya’s gym membership was $200.

It means the relationship passes through the point (0,20), not through the origin. Each proportional realtionship passes through the origin. Thus, this is not proportional relationship.
