X - 15 + 30 - 12 = 18;
Then x - 15 + 18 = 18;
x + 3 = 18;
x = $15 ( money has Ming-Li to begin with ).
He makes 3 batches of cookies...each batch contains 12 cookies...

He wants to give the same amount of cookies to all of his 20 coworkers...

27 prime factors: 9*3 prime factors of 9: 3*3
117 prime factors: 39*3 prime factors of 39: 13*3
that would make 3 the greatest common factor. for the other ones break down the numbers into the smallest amount and see which largest factor both numbers have in common.

Answer:
2000 times 3.5% is 70, so in one year you would have 2070 dollars. 3.5 divided by 3 is about 1.16 (the six repeats), so for the next 1/3 year you would do 2070 times 1.16 percent which is 30. So, then, 2070 plus 30 is 2100 dollars in the saving account.
