Juan is a software salesperson. His base salary is $2300 and he makes 70$ more for every copy of History is Fun he sells. His total pay, P (in dollars), after selling copies is c given by the following. P=2300 + 70c
(a) What is Juan's total pay if he sells 22 copies?
(b) If Juan's total pay is $4610, how many copies did he sell?

(a) $3840   (b) 33 copies

Explanation:

Note: Here P refers to total money earned, c refers to copies sold.

(a)

using the given equation:

P = 2300 + 70c

P = 2300 + 70(22)

P = 2300 + 1540

P = 3840

Juan's total pay is $3840 if he sells 22 copies.

(b)

2300 + 70c = 4610

70c = 4610 - 2300

70c = 2310

c = 33

He sold 33 copies to earn total $4610.
