When baking 25 loaves -

Profit = $5 - $4 = $1 for 25 loaves irrespective of the demand of 25, 50, or 75.

EMV = $1 * 25 = $25

When baking 50 loaves -

Profit = $1 for 25 loaves and -$4 for leftover 25 loves when the demand of 25 (p = 0.3)

=> Profit = -$75 for p = 0.3

Profit = $5 - $4 = $1 for 50 loaves for the demand of 50 or 75 (p = 0.25 + 0.45 = 0.7)

EMV = -$75 * 0.3 + $50 * 0.7  = $12.5

When baking 75 loaves -

Profit = $1 for 25 loaves and -$4 for leftover 50 loves when the demand of 25 (p = 0.3)

=> Profit = -$175 for p = 0.3

Profit = $1 for 50 loaves and -$4 for leftover 25 loves when the demand of 50 (p = 0.25)

=> Profit = -$50 for p = 0.25

Profit = $5 - $4 = $1 for 75 loaves for the demand of 75 (p = 0.45)

EMV = -$175 * 0.3 - $50 * 0.25 + $75 * 0.45 = -$31.25

Since the EMV for baking 25 loaves is maximum,  

The bakery should bake 25 loaves of bread every morning.
