Answer

Explanation:

Step1: Usar fórmula de tasa de inflación

La fórmula para calcular la tasa de inflación es $Tasa\ de\ inflación=\frac{P_2 - P_1}{P_1}\times100%$, donde $P_1$ es el precio inicial y $P_2$ es el precio final.

Step2: Calcular para opción A

$P_1 = 325$, $P_2=328$. Entonces $\frac{328 - 325}{325}\times100%=\frac{3}{325}\times100%\approx 0.92%$.

Step3: Calcular para opción B

$P_1 = 0.75$, $P_2 = 0.78$. Entonces $\frac{0.78 - 0.75}{0.75}\times100%=\frac{0.03}{0.75}\times100% = 4%$.

Step4: Calcular para opción C

$P_1=10$, $P_2 = 10.03$. Entonces $\frac{10.03 - 10}{10}\times100%=\frac{0.03}{10}\times100%= 0.3%$.

Step5: Calcular para opción D

$P_1 = 500$, $P_2=515$. Entonces $\frac{515 - 500}{500}\times100%=\frac{15}{500}\times100% = 3%$.

Answer:

D. In year 1, the price of a sofa is $500.00. In year 2, the same sofa costs $515.00.
