Question

Christine is a software saleswoman. Let y represent her total pay (in dollars). Let x represent the number of copies of Math is Fun she sells. Suppose that x and y are related by the equation y = 90x + 2300. Answer the questions below. What is the change in Christine's total pay for each copy of Math is Fun she sells? $ What is Christine's total pay if she doesn't sell any copies of Math is Fun? $

Answer 1

Explanation:

let the number of copies she sells = x

let her total pay = $y

the relation between x and y is described the equation,

y = 90x + 2300

a)

change in Christine's total pay for each copy of math is fun she sells:

change will be 90 times number of copies she sells and then added to the constant 2300

b)

if number of copies she sells, x = 0

Christine's total pay, y = 90(0) + 2300

= 0 + 2300

= $2300
