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 thisequation to find his total pay if he sells 21 coples of Math is Fun.Equation:8 O=Dxs ?Total pay if Juan sells 21 coples: s] How do I get the answer

Answer:The needed equation  relating P to N is   P =  $2300 + 90 NHis total pay if he sells 21 copies of Math is Fun is  4,190.Step-by-step explanation:The base salary of Juan = $2300The earning on per copy sold = $ 90P : His Total PayN : Number of books copies he sells.Noe, here his earnings per copy sold = $90So, the total earnings after selling N copies  = N ( earning after 1 copy) =  N ( $90)  = 90 NTOTAL EARNINGS  = BASE SALARY + MONEY EARNED after selling N copies or, P =  $2300 + 90 NSo, the needed equation  relating P to N is   P =  $2300 + 90 NNow, in second case: N = 21So, P = 2300 +  90 N = 2300 + 90 (21)           =  2300 + 1890=  4,190 or, P = 4,190Hence, his total pay if he sells 21 copies of Math is Fun is  4,190.
