Answer:
3 bags of chocolate chips
Step-by-step explanation:
72 cookies is equal to 6 dozen cookies. 18÷6 = 3. So, we have to multiply the 1 bag of chocolate chips by 3 to get the total amount of chocolate chips. 1×3=3 so it takes 3 bags of chocolate chips to make 18 dozen cookies.
Second step.
To find this, have all the 'ups' as positives and all the 'downs' as negatives, setting up an equation like this:
7 - 3 + 8 - 10 = 2
Hope this helps!
