Javelin Bakery should make 38 breads on Saturday morning.
To determine how many breads Javelin Bakery should make on Saturday morning, we need to consider the demand for the walnut-raisin bread and the cost of production.
Based on the information provided, the demand for the bread can be modeled by a uniform distribution with a lower bound of 31 and an upper bound of 45.
Since Javelin Bakery charges $6 for a loaf of bread and it costs them $3 to make one loaf, it is profitable for them even if they sell the bread for a lower price of $2 on Sunday.
To find the optimal number of breads to make, we need to calculate the expected value of the demand distribution.
The expected value of a uniform distribution is given by the formula: (lower bound + upper bound) / 2.
In this case, the expected value is (31 + 45) / 2 = 38.
Therefore, Javelin Bakery should make 38 breads on Saturday morning.
