Need help with this continuity problem.
ira [324]

In order to be continuous everywhere, we only need to satisfy continuity at x=10. For that to happen, we need to have

\displaystyle\lim_{x\to10^-}f(x)=\lim_{x\to10^+}f(x)=f(10)

By the function's definition, f(10)=2(10)-2=18. Compute the limits:

\displaystyle\lim_{x\to10^-}f(x)=\lim_{x\to10}2x-2=18

\displaystyle\lim_{x\to10^+}f(x)=\lim_{x\to10}-8x+b=-80+b

So we must have

18=b-80\implies b=98

Step-by-step explanation:

Since percents are decimals, we can figure out the tip by multiplying the total by the decimal percent.

11 x .20 = 2.2

If you need the tip, it's $2.20.
