Question

A company produces accounting software programs for home computers. The company

has found that A, the weekly profit in dollars it makes for selling x programs, is given by
the equation below. A=-0.2x2 + 25x - 400 For what values of x would the company
make a weekly profit of $1,500?

Answer 1

• No solution

Explanation:

Given function:

• A = -0.2x² + 25x - 400

Find x when A = 1500

• -0.2x² + 25x - 400 = 1500
• -0.2x² + 25x - 1900 =0
• x² - 125x + 9500 = 0
• D = √125² - 4*9500 = √-22375

This give no solution as discriminant is negative
