Problema Solution

It costs a manufacturer $8.45 to produce sunglasses that sell for $23.99. How many pairs of sunglasses must the manufacturer sell to make a profit of $13,986?

Answer provided by our tutors

let 'x' represent the number of sunglasses sold, then the profit can be expressed by this linear equation:

profit = 23.99x - 8.45x = 15.54x


we want a profile of 13986:

13986 = 15.54x

x = 13986 / 15.54 = 900


900 sunglasses must be sold
