Amie published her first book. She was given $20,000 and an additional $0.15 for each copy that sold. Her earnings,d, in dollars,from the publication of the book are given d=20,009 + 0.15n where n is the number of copies sold. During the first year, Amie earned $22,100 from the publication and the sale of her book. How many copies of her book were sold?

Sagot :

d=20,009 + 0.15n
$22,100 = 20,009 + 0.15n
$2091 = 0.15n
n = 2091/.15 = 13940

Answer: 139 copies of her book were sold.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Earnings (d)  

  • d= 20,009+0.15n

Where "n" is the number of copies sold.

If she earned $22,100, we have to replace the value of d by the number given:

22,100 = 20,009 +0.15 n

Solving for n

22,100-20,009 = 0.15n

2,091=0.15n

2,091/15=n

139.4=n

n≅139 books (rounded)
