Answer :

Answer: The answer is 388$

Step-by-step explanation:

First we need to know our domain and range. our domain is POUNDS and range is TOTAL COST of the delivery AND briskit. Next, we need to find how much the briskit cost by itself. The brisket is 38 pounds.  So to do this, we use need to subtract; y - x = briskit cost. It would look like this if you plug in the units:

304 - 38=266

Now we are going to find how much EACH POUND COSTS. To do this, all we have to do is divide the briskit cost and how much the briskit weighs:

266/38=7

Now that we know how much the briskit cost and how much each briskit weighs, we are going to use the formula y=mx+b so that we can plug in 50 pounds for our x. It would look like this if you plug in the units:

y= 7x+ 38

y= 7(50) + 38= 388$

*Don't forget the dollar sign :) *
