Question

in 1991 vhr was 50 dollars today they are 12 dollars what is the percent decrease

Answer 1

Answer:

76%

Explanation:

The percentage of the decrease can be calculated using the following equation:

$\text{ \% decrease = }\frac{v_i-v_f}{v_i}\times100$

Where vf is the final value and vi is the initial value. So, we can replace vf by 12 dollars and vi by 50 dollars. So:

$\begin{gathered} \text{ \% decrease = }\frac{50-12}{50}\times100 \\ \text{ \% decrease = }76\text{ \%} \end{gathered}$

So, the percentage of the decrease is 76%.
