Answer:percent increase in cupcake sales from Friday to Saturday= 34%
Step-by-step explanation:
Step 1
Percent increase = Increase in cup cakes/ Old amount of cupcakes x100
Cupcakes sold on Friday = 19 3/4
Cupcakes sold on Saturday = 261/2
Increase in sales =26 1/2 -- 19 3/4 ( we will change to decmal for easy solving)
=26.5 - 19.75= 6.75 or 6 3/4
Step 2
Percentage increase = (6 3/4)/ (19 3/4) x100
Percentage increase = 6.75/19.75 x 100
Percentage increase =0.341 x100 = 34%
