Answer 1

Answer:

Option B. 66 cookies

Step-by-step explanation:

The complete question is

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?

step 1

we know that

There are a total of 150 chocolate chips for each tray of cookies

Find out the number of chocolate chips if Bella  is baking 2 trays

so

using proportion

Let

x ----> the number of chocolate chips

$\frac{150}{1}=\frac{x}{2}\\\\x=150(2)\\\\x=300\ chocolate\ chips$

step 2

we know that

She uses 1 1/10 cups of flour for every 50 chocolate chips used.

Find out the number of cups of flour for 300 chocolate chips

so

using proportion

Let

x ----> the number of cups of flour

Convert mixed number to an improper fraction

$1\frac{1}{10}\ cups=\frac{1*10+1}{10}=\frac{11}{10}\ cups$

$\frac{(\frac{11}{10})}{50}=\frac{x}{300}\\\\x=\frac{66}{10}\ cups$

Simplify

$\frac{66}{10}\ cups=\frac{33}{5}\ cups$

step 3

we know that

It takes 3/5 of a cup of flour to bake 6 cookies

Find out the number of cookies she bake for 33/5 cups of flour

so

using proportion

Let

x -----> the number of cookies

$\frac{6}{(3/5)}=\frac{x}{(33/5)}\\\\x=6(33)/3\\\\x=66\ cookies$
