Question

30% of 50(20-2+18+20×3÷5)

Answer 1

Answer:

$30\% \times 50(20 - 2 + 18 + 20 \times \frac{3}{5} ) \\ =\frac{30}{100} \times 50((20 - 2) + 18 + (20 \times \frac{3}{5} )) \\ = \frac{3}{10} \times 50(18 + 18 + 12) \\ = \frac{3}{10} \times 50(48) \\ = \frac{3}{10} \times 2400 \\ = \: \: \underline{ \underline{720}}$
