3. the following data shows the relationship between the number of miles a taxi drives and the cost. is this relationship proportional?\nmiles: 2, 5, 8\ncost ($): 8, 14, 20

Answer

Explanation:

Step1: Calculate cost - per - mile ratios

For the first data - point: $\frac{8}{2}=4$

Step2: Calculate cost - per - mile for second data - point

For the second data - point: $\frac{14}{5}=2.8$

Step3: Calculate cost - per - mile for third data - point

For the third data - point: $\frac{20}{8}=2.5$

Step4: Check for proportionality

Since $4\neq2.8\neq2.5$, the ratios are not equal.
