You sell bobble heads online. You need to pay $120 to get the web space and website name. You pay $12 for each bobble head. You will sell them for $15 each. How many bobble heads do you have to sell before you break even?

Respuesta :

Americ
x= number of bobble heads
120+3x= amount already spent
15x= amount needed to sell


EQUATION:
120 + 12x= 15x

Subtract 12x from both sides
120= 3x

divide both sides by 3
40= x

You need to sell 40 bobble heads to break even (make as much as you already spent).

Check:
120 + 12x= 15x
120 + 12(40)= 15(40)
120 + 480 = 600
600=600

Hope this helps! :)
