Question

to figure out how many vacation days he had left to use, darell looked over his old calendars to figure out how many days of vacation he had taken each year. vacation days taken by darell year vacation days 2011 20 2012 25 2013 20 2014 10 2015 8 according to the table, what was the rate of change between 2011 and 2013? vacation days per year

Explanation:

Step1: Identificar los valores

En 2011, \( y_1 = 20 \) días de vacaciones. En 2013, \( y_2 = 20 \) días de vacaciones. El cambio en el tiempo \( \Delta x=2013 - 2011=2 \) años.

Step2: Aplicar la fórmula de tasa de cambio

La fórmula de tasa de cambio es \( \text{Tasa de cambio}=\frac{y_2 - y_1}{x_2 - x_1} \). Sustituyendo los valores: \( \frac{20 - 20}{2}=\frac{0}{2}=0 \).

Answer:

\( 0 \)
