Answer:
its D
Step-by-step explanation:
First problem
The recipe is written for 3 dozen cookies.
Hew wants to make 12 dozen cookies.
12 dozen is 4 times 3 dozen, so multiply each amount by 4 to make 12 dozen cookies.
4 eggs * 4 = 16 eggs
1/2 cup chocolate chips * 4 = 2 cups chocolate chips
Second problem
Let's start from the end.
There were 40 apples left on the tree.
Sally picked 1/3 of the apples that were left for her.
40 apples were left after Sally finished.
Since Sally picked 1/3 of the apples, she left 2/3 of the apples on the tree.
2/3 of the apples were 40 apples. 1/3 is 20 apples, so the number of apples left for Sally is 60 apples. Before Sally started, there were 60 apples.
Bill had picked 1/2 the apples, which means he left half of them. He left 60. That means to original number was 120 apples.
Answer: 120 apples.

Answer:
7^8 =5764801 * 7^3 =343 * 7^4 =2401 ÷ 7^9 = 40353607 * 7^5 =16807
5764801 *343 *2401 ÷ 40353607 *16807
=4747561509943 ÷ 678223072849 = 7
