Ti-83 graph proves it.
To increase by 2% you multiply to get 1102*0.02=22.04. You then add that to 1102, getting 1124.04. To then decrease it by 1% you multiply to get 1124.04*0.01=11.24. Subtract 11.24 from 1124.04 to get a final answer of 1112.8
Solution
The counselor has 12 electives courses (e.g. art, band, PE, etc.) to choose from and must select 2 ordered classes for each 6th grade student.
Let S be the sample space.
Then, n(S) = 12C2 = (12 x 11) ÷ (2 x 1 ) = 132 ÷ 2 = 66
![Then, n(S) = 12C2 = (12 x 11) ÷ (2 x 1 ) = 132 ÷ 2 = 66](https://tex.z-dn.net/?f=Then%2C%20n%28S%29%20%3D%2012C2%20%3D%20%2812%20x%2011%29%20%C3%B7%20%282%20x%201%20%29%20%3D%20%20132%20%C3%B7%202%20%3D%20%2066)
Sixty six (66) ways can the counselor arrange the last 2 periods of the day for the 6th grade students
The answer is: 7x
