Question

Si A = 30% de 50 y B = 10% de 2A. Calcula el valor de A + B

Answer 1

Respuesta:

Valor de A

$30\% \times 50 = 50 \times \frac{30}{100} \\ \\ \frac{1500}{100} = 15$

Valor de B

$10\% \times 2a = 10\% \times 2(15) \\ \\ 10\% \times 30 = 30 \times \frac{10}{100} \\ \\ \frac{300}{100} = 3$

A+B

$15 + 3 = 18$
