Answer:
12
Step-by-step explanation:
Required algebraic expression is 3/z
Answer:
It should be 46.20
Step-by-step explanation:
You're rounding to the nearest hundredth. So you have 46.1979 to start out with. Then you count 2 places so you end at the 1st 9. Well, behind the 9 is a 7 so you round up and get 20
Answer:
Mixed numbers have a whole number followed by the fraction (2 1/2). You would say "two and one half." The other format is an improper fraction where the numerator is greater than the denominator (5/2). Mathematicians would say that is five halves.
Karen has a base salary that is $2100 and does not depends on how many copies she sells.
Additional to the base salary, she gets $50 for each copy she sells, so we can write this additional salary as 50*N, being N the number of copies she sells.
Then, we can write the total pay P as:
![P=2100+50N](https://tex.z-dn.net/?f=P%3D2100%2B50N)
Then, if N=22, we can calculate the total pay as:
![P(22)=2100+50\cdot22=2100+1100=3200](https://tex.z-dn.net/?f=P%2822%29%3D2100%2B50%5Ccdot22%3D2100%2B1100%3D3200)
Answer:
The equation relating P and N is P=2100+50N.
The total pay when she sells 22 copies is $3,200.
