Answer:
B. $56.24
Step-by-step explanation:
74.99 x 7.5%=5.62425
5.62425 x 10= 56.24
![y = mx+b\\\\[m is the slope, b is the y-intercept]\\\\y=\frac{2}{3}x+5\\](https://tex.z-dn.net/?f=y%20%3D%20mx%2Bb%5C%5C%5C%5C%5Bm%20is%20the%20slope%2C%20b%20is%20the%20y-intercept%5D%5C%5C%5C%5Cy%3D%5Cfrac%7B2%7D%7B3%7Dx%2B5%5C%5C)
That means 2/3 is the slope and 5 is the y-intercept.

Step-by-step explanation:
Inflection points are where a function changes concavity (the second derivative changes signs). At x = 4, f"(x) goes from negative to positive, so that's an inflection point. However, at x = 8, we don't know if f"(x) changes signs or not. So we can't say that that's an inflection point.
