Answer:
B) 174
Step-by-step explanation:
30+6*2 because she already has 30 made and 2 dozen per 6 hours. So to find how any dozen in the 6hrs you do 2*6 = 12. So 12 dozen in 6hrs. 1 dozen is 12 cookies. To find how much cookies in 12 dozen you do 12*12 = 144. Now you do 144+30 because she bakes 30 earlier and she will bake 144 in those 6 hours. 144+30 = 174. So Frida will have 174 cookies. So the answer is B) 174.
