Profit is the difference between revenue and cost. The revenue, in dollar, of company that manufactures television can be modeled by the polynomial 3x²+180x. The cost, in dollar, of producing the televisions can be modeled by 3x²-160x+300.The variable x is the number of televisions sold. If 150 televisions are sold ,what is the profit? C)$50,700

The profit in this case is equal to $50,700.

Step-by-step explanation:

As the problem stated profit is the difference between revenue and cost, in this case we have:

So the profit will be the difference between these two functions.

In order to find the profit when 150 televisions are sold we need to make x equal 150.

The profit in this case is equal to $50,700.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
