Answer:

B. 66 cookies

Step-by-step explanation:

We are given three ratios:

3/5 cups of flour per 6 cookies

1 1/10 cups of flour per 50 chocolate chips

150 chocolate chips per tray

We need to find the number of cookies in 2 trays.

2 tray × (150 chocolate chips / tray) = 300 chocolate chips

300 chocolate chips × (1 1/10 cups flour / 50 chocolate chips) = 6.6 cups flour

6.6 cups flour × (6 cookies / 3/5 cups flour) = 66 cookies
