Juan is a software salesman. His base salary is $2300, and he makes an additional $90 for every copy of Math is Fun he sells.
Let P represent his total pay (in dollars), and let N represent the number of coples of Math is Fun he sells. Write an equation relating P to N. Then use this
equation to find his total pay if he sells 21 coples of Math is Fun.

Answer:

The needed equation  relating P to N is   P =  $2300 + 90 N

His total pay if he sells 21 copies of Math is Fun is  4,190.

Step-by-step explanation:

The base salary of Juan = $2300

The earning on per copy sold = $ 90

P : His Total Pay

N : Number of books copies he sells.

Noe, here his earnings per copy sold = $90

So, the total earnings after selling N copies  = N ( earning after 1 copy)

=  N ( $90)  = 90 N

TOTAL EARNINGS  = BASE SALARY + MONEY EARNED after selling N copies

or, P =  $2300 + 90 N

So, the needed equation  relating P to N is   P =  $2300 + 90 N

Now, in second case: N = 21

So, P = 2300 +  90 N = 2300 + 90 (21)  

        =  2300 + 1890=  4,190

or, P = 4,190

Hence, his total pay if he sells 21 copies of Math is Fun is  4,190.
