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%

2 consecutive odd integers.....x and x + 2.....the product means multiply....the sum means add.
x(x + 2) = 4(x + x + 2) - 1
x^2 + 2x = 4(2x + 2) - 1
x^2 + 2x = 8x + 8 - 1
x^2 + 2x = 8x + 7
x^2 + 2x - 8x - 7 = 0
x^2 - 6x - 7 = 0
(x - 7)(x + 1) = 0
x - 7 = 0 x + 2 = 7 + 2 = 9
x = 7
x + 1 = 0 x + 2 = -1 + 2 = 1
x = -1
there can be 2 answers for this....
(1) 7 and 9
(2) -1 and 1
