Answer:

She will earn $25 each week. Stacey's rate of change amounts to $25.

After 12 weeks, she will have accumulated $300.

Step-by-step explanation:

Given: Stacey holds a part-time position at the bike shop. She saves $100 every four weeks for a vehicle.

To determine:Stacey's weekly savings after four weeks and the total after 12 weeks is what?

Solution:

In every four weeks, she puts away $100.

In one week, she saves \frac{\$100}{4}.

Thus, in one week, she saves $25.

After a span of 12 weeks, she saves

.\$25\times 12

By the 12th week, she will have $300 saved.

The rate of change is

r=\frac{100-25}{4-1}

r=25

She will earn $25 each week. Stacey's rate of change amounts to $25.

After 12 weeks, she will have accumulated $300.
