Problem
The total in-store price for an appliance is 
99.99
$
and a one-time shipping and handling charge of 9.98
\mathrm{(A) \ 6 } \qquad \mathrm{(B) \ 7 } \qquad \mathrm{(C) \ 8 } \qquad \mathrm{(D) \ 9 } \qquad \mathrm{(E) \ 10 } 
99.99 - (29.98*3 + 9.98) = 99.99 - 99.92 = .07 \Rightarrow \mathrm{(B)}$==Solution 2==
Alternately, the in-store price is$ (Error compiling LaTeX. Unknown error_msg)1
100.00$dollars.
The television price is$ (Error compiling LaTeX. Unknown error_msg)3\cdot 2 + 2 = 8
30.00 \cddot 3 + 10.00 = 100.00$dollars.
Therefore, the difference is$ (Error compiling LaTeX. Unknown error_msg)8 - 1 = 7
\mathrm{(B)}$
