The operation that should be completed first to find the value of the expression is 6 - 3
<h3>How to determine the first expression?</h3>
The equation is given as:
12 + 30 = (6 - 3) +1
By the rule of BODMAS, the first expression that should be evaluated is the expression in the bracket
This means that we solve for 6 - 3, first.
Hence, the operation that should be completed first to find the value of the expression is 6 - 3

Answer:
$74
Step-by-step explanation:
25*32 will be the total amount he spent at first. ($800)
He sells 22 calculators at 40$, 22*40 = 880.
He was unable to sell 3, and he had to pay 2$ per (2*3 = 6)
He had an 80 dollar profit before he returned them, (880-800).
Then he returned three for 6$ (80-6)
His end profit was 74.
41 Fahrenheit is 5 Celsius
![nP3=\frac{n!}{(n-3)!}](https://tex.z-dn.net/?f=nP3%3D%5Cfrac%7Bn%21%7D%7B%28n-3%29%21%7D)
![17(nP2)=17(\frac{n!}{(n-2)!})](https://tex.z-dn.net/?f=17%28nP2%29%3D17%28%5Cfrac%7Bn%21%7D%7B%28n-2%29%21%7D%29)
Therefore we can write the equation as follows:
![\frac{n!}{(n-3)!}=17(\frac{n!}{(n-2)!})](https://tex.z-dn.net/?f=%5Cfrac%7Bn%21%7D%7B%28n-3%29%21%7D%3D17%28%5Cfrac%7Bn%21%7D%7B%28n-2%29%21%7D%29)
Dividing both sides by n!, we get:
![\frac{1}{(n-3)!}=\frac{17}{(n-2)!}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%28n-3%29%21%7D%3D%5Cfrac%7B17%7D%7B%28n-2%29%21%7D)
![\frac{(n-2)!}{(n-3)!}=17](https://tex.z-dn.net/?f=%5Cfrac%7B%28n-2%29%21%7D%7B%28n-3%29%21%7D%3D17)
Therefore n - 2 = 17 and n = 19
The answer is: n = 19
