Basta organizarmos e calcular .

Explicação passo-a-passo:

Temos :

$\large \boxed{ \boxed{ \: \: \: 300 \times 15\% = \boxed{ \boxed{ \bm 4 \bm 5 \: \: \: }}}} \\ \\ \large \boxed{ \boxed{1.200 \times 80\% = \boxed{ \boxed{ \bm 9 \bm 6 \bm 0}}}} \\ \\ \large \boxed{ \boxed{ 5.000 \times 9\% = \boxed{ \boxed{\bm 4 \bm5 \bm 0 }}}}\\ \\ \large \boxed{ \boxed{ 250 \times 31\% = \boxed{ \boxed{ \bm 7 \bm 7 \bm . \bm 5}}}}$

Assim temos a resposta correta .
