(1) Yes, $$ (b+12) \div 8 $$ can be written as $$ \frac{b+12}{8} $$ because division is the same as a fraction. (2) a. $$ 3.1n - 5 $$; b. $$ \frac{12}{x} + 4 $$; Variables: $$ g $$; Coefficients: $$ 0.60 $$; Terms: $$ 165 $$ (weekly salary), $$ 0.60g $$ (bonus from gift cards), $$ g $$ (number of gift cards sold).
