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

$18=b-80\implies b=98$

<em>store y has the better buy.</em>

store x -- 3.04 ÷ 3 = $1.01 per bag

store y -- 3.60 ÷ 5 = $0.72 per bag

store z -- $0.78 per bag

store y cost the least so it is the best option.
