Answer:
$2740

Let P = total pay
Let n = number of copies sold

P = $1900 + 40n
P = $1900 + 40(21)
P = $1900 + $840
P = $2740

Answer:

2740 is your total; p = 40n + 1900 is your equation.

Explanation:

"p" represents total pay; "n" represents the number of copies he sells.

Base salary is 1900, and each copy sold gives him an extra 40

p = 40n + 1900 is your equation.

If he sells 21 copies. Plug in 21 for n

p = 40n + 1900

p = 40(21) + 1900

Simplify. Remember to follow PEMDAS. First, multiply, then add.

p = 40(21) + 1900

p = 840 + 1900

p = 2740
