Question

Bella is baking chocolate chip cookies for an event. It takes 3/5 of a cup of flour to bake 6 cookies. She uses 1 1/10 cups of flour for every 50 chocolate chips used. There are a total of 150 chocolate chips for each tray of cookies. If Bella is baking 2 trays of chocolate chip cookies, then how many cookies will she bake in total?

Answer 1

300 chocolate chips is 6 batches of 50 chips each

(300 chocolate chips = 6 batches @ 50 chips ea)

Each batch of 50 chips = 1.1 cups of flour

Therefore 6 batches @ 1.1 cups ea = 6.6 cups of flour

-----------------

0.6 cups (3/5 cups) of flour makes 6 cookies

6.6 cups of flour is 11 times more than that.

(0.6 x 11 = 6.6)

So she can make 11 times as many cookies.

(11 x 6 cookies = 66 cookies)

Answer:

Bella can make 66 cookies

(minus the three cookies that SumDude ate)
