1. find the price that is used to buy the fabric which by 12.5 times $4.50 is $56.25 2. then you have to find how many different dog beds she can make by doing 12.5/2.5 which is 5 different dog beds 3. then you have to multiply the amount she can sell with the price that she will sell them for by doing 5 times $17.50 which is $87.50 4.
