The price of a reusable bottle rises from 80 dollars to 92 dollars. What is the percent increase? Enter the number of percent.
Respuesta correcta
15
Explicación
The change is 92 - 80 = 12 dollars, and 12 / 80 x 100 = 15%. Dividing 12 by 92 would use the final price as the base and understate the increase.
