In an effort to increase sales of spinach rolls, a vendor offered samples at a grocery store. The store sold an average of 10 boxes a day without offering samples. On the day the vendor offered samples, the store sold 25 boxes. What was the percent increase in sales of spinach rolls when samples were offered?

Respuesta :

There was 150% increase in sales of spinach rolls when samples were offered.

Step-by-step explanation:

Given,

Number of boxes sold without sample offering = Old value = 10

Number of boxes sold with sample offering = New value = 25

Change = New value - Old value

Change = 25 - 10 = 15

Percent increase = [tex]\frac{Change}{Old\ value}*100[/tex]

Percent increase = [tex]\frac{15}{10}*100=\frac{1500}{10}[/tex]

Percent increase = 150%

There was 150% increase in sales of spinach rolls when samples were offered.
