Explanation:

Given : Stacey has a part-time job at the bike shop. She saves $100 every four weeks for a new car.

To find : Her rate of change After four weeks, she will have $ After 12 weeks , she will have $ per week Stacey's rate of change is $ ?

Solution :

In every four weeks she saves $100.

In every one week she save
`(\$100)/(4)`.

In every one week she save $25.

After 12 week she save
`\$25* 12`.

After 12 week she save $300.
