Sagot :

Answer: 34.18%  

Step-by-step explanation:

Given: On Saturday, Number of cupcakes sold = [tex]26\dfrac12[/tex] dozens

= [tex]\dfrac{53}{2}[/tex] dozens

[tex]=\dfrac{53}{2}\times12[/tex]    [  1 dozen = 12 items]

[tex]=53\times6\\\\=318[/tex]

On Friday, Number of cupcakes sold = [tex]19\dfrac34[/tex] dozens

= [tex]\dfrac{79}{4}[/tex] dozens

[tex]=\dfrac{79}{4}\times12[/tex]    [  1 dozen = 12 items]

[tex]=79\times3\\\\=237[/tex]

Increase in cupcakes = 318-237=81

Percent increase in cupcakes sales from Friday to Saturday = [tex]\dfrac{81}{237}\times100[/tex]

= 34.18%   (approx)

The approximate percent increase in cupcake sales from Friday to Saturday = 34.18%
