Answer:

a. x is the width of the fence in feet and y is the length of the fence in feet , f = 2x+ 2y equation represents that the fence is twice the width and twice the length , x>10 represents that the width should be atleast 10 feet , y >8 represents that the length should be at least 8 feet , 3f<120 represents the cost constraint. it says that the fencing cost $3 per foot and should cost less than or equal to 120 . b. yes, i agree. this is because the inequality f>0 implies that the length of the fencing should be greater than 0.

The amount of sales tax on a new car is directly proportional to the purchase price of the car. Victor bought a new car for $30,
Airida [17]

Answer:

Rita paid 47,500 dollars for the purchase price.

Step-by-step explanation:

We are given the sales tax on a new car is directly proportional to the purchase price of the car which means there is is something k such that

when you multiply it to the sales tax you get the purchase price.

Let's set this equation:

y=kx

Let y represent the purchase price and x the sales tax.

The second sentence tells us that (x,y)=(1500,30000).

We can plug this into y=kx to find the constant k.  (Constant means it stays the same no matter what the input and output is).

So we have:

30000=k(1500)

300    =k(15)      I went ahead and divided previous equation by 100.

Now divide both sides by 15:

300/15=k

Simplify:

20=k

So the equation to use the answer the question is

y=20x

where y is purchase price and x is sales tax.

So we want to know the purchase price on a car if the sales tax is 2375.

So replace x with 2375:

y=20(2375)

y=47500

romanna [79]

Answer:

$185

Step-by-step explanation:

The first ten suits sold for 10×$250 = $2,500

commission = 5% of $2,500 = 0.05×$2,500 = $125

The next three suits sold for 3×$250 = $750

commission = 8% of $750 = 0.08×$750 = $60

Total commissions = $125+$60 = $185

There are several errors in the question. If you are using voice recognition, you are better off typing the question manually.
