Question 1185394: Frances likes to make flour cookies. These cookies need so much flower that  of the cookie
itself is flour. The rest is baking powder, baking soda, butter, and sugar.
“Mom, I’m going to make a batch for Boo,” says Frances.
“Boo? You spoil your dog!” laughs here mom,
One cookie weighs 1.3 ounces. She has 12 ounces of flour and plenty of the rest of the
ingredients. How many cookies can she make?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! if a cookie weights 1.3 ounces and 6/10 of the weight of the cookie is flour, then the amount of flour in one cookie is 6/10 * 1.3 - .78 ounces.
if she has 12 ounces of flour, then divide that by .78 to get 12/.78 = 15.38461538.
she can make 15.38461538 cookies with 12 ounces of flour.
if she only wants to make whole number of cookies, then she can make 15 cookies.
she would have .38461538 * the amount of flour in a cookie left.
that would be .38461538 * .78 = .3 ounces of flour.
15 cookies * .78 ounces of flour each is equal to 11.7 ounces of flour.
12 ounces - 11.7 ounces of flour = .3 ounces of flour left over.
your solution is that she can make 15 cookies with .3 ounces of flour left over.
if she is willing to make partial cookies, then she can make 15.38461538 cookies with 12 ounces of flour.
