Ineed algebra the revenue r (in thousands dollars) for a business is modeled by the equation r=x3−6x2+x+75 , where x is the number of years since 2000. the cost c (in thousands dollars) for this business is modeled by the equation c=x2−70x . which equation represents the profit, p, for this business?

Given that the revenue R (in thousands dollars) for a business is modeled by the equation

Where x represents the number of years since 2000.

Cost C (in thousands dollars) for this business is modeled by the equation

Now question is asking for the profit equation.

We know that profit occurs when Revenue is more than the cost.

So basically profit is the difference of "revenue" and "cost"

Profit P = R - C

Hence final answer is .

worked it out i believe

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
