Question

Raymond's bake shop sold 26 1/2 cupcakes on Saturday on Friday the bake shop sold 19 3/4 dozen cupcakes what is the approximate percent increase in cupcake sales from Friday to Saturday

Answer 1

Answer: 34.18%

Explanation:

Given: On Saturday, Number of cupcakes sold =
`26\frac12` dozens

=
`(53)/(2)` dozens

`=(53)/(2)*12` [ 1 dozen = 12 items]

`=53*6\\\\=318`

On Friday, Number of cupcakes sold =
`19\frac34` dozens

=
`(79)/(4)` dozens

`=(79)/(4)*12` [ 1 dozen = 12 items]

`=79*3\\\\=237`

Increase in cupcakes = 318-237=81

Percent increase in cupcakes sales from Friday to Saturday =
`(81)/(237)*100`

= 34.18% (approx)

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