Question

aumento:
-> salário: 3200 reais
teve um aumento de 20%.
qual o valor final?

Explanation:

Identify the given values

We are given:

• Initial salary: \(S = 3200\) reais
• Percentage increase: \(p = 20\%\)

Calculate the increase amount

To find the increase, calculate \(20\%\) of \(3200\):

$$ \text{Increase} = 3200 \times \frac{20}{100} = 3200 \times 0.2 = 640\text{ reais} $$

Calculate the final value

Add the increase to the initial salary:

$$ \text{Final Value} = 3200 + 640 = 3840\text{ reais} $$

Alternatively, multiply by the growth factor \(1 + 0.2 = 1.2\):

$$ \text{Final Value} = 3200 \times 1.2 = 3840\text{ reais} $$

Answer:

\(3840\) reais
