Hester sells televisions. She earns a fixed amount for each television and an additional $ 15 if the buyer gets an extended warranty. If Hester sells 16 televisions with extended warranties, she earns $ 1 comma 200. How much is the fixed amount Hester earns for each television?

Where y is the total amount earned, m the amount for each extended warranty and b the fixed cost and x the total amount of TVs

For this case the value of x = 16 since we have 16 Tvs with extended warranties and we can do this:

and solving for b we got:

And then we can conclude that she earns 60 for each TV

Step-by-step explanation:

Where y is the total amount earned, m the amount for each extended warranty and b the fixed cost and x the total amount of TVs

For this case the value of x = 16 since we have 16 Tvs with extended warranties and we can do this:

and solving for b we got:

And then we can conclude that she earns 60 for each TV
