You are comparing the costs of producing lamps at two different manufacturers. Company 1 charges $15 per lamp plus a $1200 flat fee. Company 2 charges $30 per pair lamp plus a $500 flat fee. How many lamps are produced when the total costs for both companies are equal? Company 1 = $15x + 1200 Company 2 = $30x + 50 Solve the following equation to determine when the total costs are equal15x +1200 = 30x + 500

Respuesta :

Charget 1

15X + 1200

Charge 2

30X + 500

Then find X, isolate X

1200 - 500 = 30X - 15X

700 = 15X

then

700/15 = X

X = 46 lamps

Answer is , 46 lamps are produced,
