Answer: She will sell the entire pie for $7.5.
Step-by-step explanation:
Given: Number of slices in each pumpkin pie = 6
Selling price for each slice = $1.25
Now , Selling price for 6 slices = 6 x (Selling price for each slice)
= 6 x $1.25
= $ 7.5
i.e. Selling price for entire pie = $ 7.5
Hence, She will sell the entire pie for $7.5.
