Baker's Flour Usage Problem

A baker is preparing a large order of cakes and needs to determine how much flour to use. The recipe requires the following: for every cake, 2.5 pounds of flour is used. The order is for 40 cakes, but the baker has only enough flour to make 75% of the order.

First, calculate the total amount of flour needed for 40 cakes. Then, determine how much flour the baker will use based on the 75% limit. Finally, if the baker decides to use the flour available instead, what percentage of the total flour needed will he end up using for the cakes he can make?
