Answer 1

Answer:

The dollar cost of the flour required to make 1 cake is:

                   $   w/(xy)

Step-by-step explanation:

It is given that:

• It takes 1 pound of flour to make y cakes.

This means that in order to make 1 cake the amount of flour required is: 1/y pound.

• The price of flour is w dollars for x pounds.

Cost of x pounds= $ w

Cost of 1 pound= $ w/x

Cost of 1/y pound= $ w/(xy)

i.e.

Cost of making 1 cake= $ w/(xy)
