Answer: 180 cookies
Step-by-step explanation: If 1.75 cups of flour is required to make a batch and the bakery used 5.25, the bakery made 3 batches, since 1.75(3) is 5.25. One dozen is 12 cookies, and there are 5 dozen cookies in each batch. If there are 3 batches, then there are 15 dozens of cookies. 15(12) is 180.

Step-by-step explanation:
1. 18^2 - 10^2 = 324 - 100 = 224
Sqt(224)=14.9666
Approximate = 14.97
2. 100 - 16 = 84
Sqrt 84 = 9.1652
Approximate = 9.17
3. 225 - 49 = 176
Sqrt 176 = 13.2665
Approximate = 13.27
4. 361 - 144 = 217
Sqrt 217 = 14.7309
Approximate = 14.73
