Answer:
45 cookies
Explanation:
Use a unit rate.
With a unit rate, we find the number of cookies that are baked using 1 scoop.
(30 cookies)/(6 scoops) = 5 cookies/scoop
The rate of 30 cookies to 6 scoops is the same as the unit rate of 5 cookies/scoop.
Now we multiply the unit rate by 9 scoops.
9 scoops * 5 cookies/scoop = 45 cookies
Answer: 45 cookies
