Based on the information given the percent of the total cost of the bike has Wu saved is 30%.
Using this formula
Total cost percentage=Amount saved/Cost×100
Where:
Amount saved=$75
Cost =$250
Let plug in the formula
Total cost percentage=$75/$250×100
Total cost percentage=30%
Inconclusion the percent of the total cost of the bike has Wu saved is 30%.

Answer:
k(-1) = 7.
Step-by-step explanation:
k(-1) is the value of the function k when x = -1.
You read this off the graph.
Find the value of the point on the graph which corresponds to x = -1. From x = -1 on the horizontal axis move straight up until you meet the graph of k. Now look horizontally to the right and read off the value on the vertical
y-axis
You'll find it is 7.
Answer:
1. C
2. B
3. D
4. A
5. B
Step-by-step explanation:
The data cannot be modeled by a linear equation because the rate of change is not constant. This can be seen in the fact that when you increase x from 1 to 2, you subtract 3 from the y-values. However, as you add 2 more, you continue to subtract 3 from the y-values. If the function were a linear function, we would likely subtract 6 from the y-values, since that would form a constant ratio.
You can even look at the fact that as we increased the x by 4, we continued to decrease the y by 3. This does not form a constant ratio, and is thus the data could not be modeled by a linear function.
