Question

A bakery uses 2 lbs of butter to make 5 dozen cookies. How many pounds of butter would be used to make 200 cookies?

Answers

  2. Answer:

    6.67lbs

    Step-by-step explanation:

    let’s write cookies as C.

    we know dozen means 12 so we multiply 5 by 12 to know how many cookies that the bakery uses 2lbs of butter for.

    That would be; 2lbs= 5×12 C

    2lbs=60C.

    now we can find how much butter is used for a single cookie(C) by dividing both sides by 60;

    \frac{2}{60}lbs=C;

    C= \frac{1}{30}lbs

    since we know what C is, we can use that in finding how much butter will be needed for 200 cookies(C)

    200C=200(\frac{1}{30}lbs)

    200C= \frac{200}{30}lbs

    200C= 6\frac{2}{3}lbs or 6.67lbs
