y = 10x + 5 is the required equation.

<u>Explanation:</u>

A family of two to go to state fair is $25

A family of six to go to state fair is $65

So the 2 points are (2,25) and (6,65)

Rate of change = (y2-y1)/ (x2-x1)

  Plugin the values, we will get,

                           = (65 - 25)/ (6-2)= 40/4 = 10

Equation can be written as,

(y - y₁) / (y₂ - y₁) = (x-x₁)/(x₂-x₁)

(y-25)/(65-25) = (x-2)/(6-2)

(y-25)/ 40 = (x-2) / 4

4(y-25) = 40(x-2)

4y - 100 = 40x - 80

4y = 40x - 80 + 100

4y = 40x + 20

Dividing the equation by 4, we will get,

y = 10x + 5 is the equation required.

Tasya [4]

Answer:

That statement is true.

Explanation:

Most companies require this type of procedures to ensure that the employees wouldn't scam the customers during the transaction process.

Restating the total and the total changes allow the guests to conduct a self-calculation for the purchase, ensuring whether the price is suitable to the price tag that provided on the counter.  This prevent the employees from giving a higher price to the customers and taking the additional amount for themselves.

Anne’s marginal income tax rate is 32 percent. She purchases a corporate bond for $19,500 and the maturity, or face value, of th
Bess [88]

Answer:

6.0%

Explanation:

Given that :

Marginal income tax rate = 32%

Interest rate before taxes = 8.8%

Annual after-tax rate of return if bond matures in 10 years will be the same as the annual after tax rate of return since the annual rate is constant.

Hence,

Annual after tax rate of return = Interest rate × (1 - tax rate)

Annual after tax rate = 8.8% × (1 - 32%)

Annual after tax rate = 0.088 × (1 - 0.32)

Annual after tax rate = 0.088 × 0.68

Annual after tax rate = 0.05984

= 0.05984 × 100%

= 5.984% = 6.0%

What would happen if a supplier charged more than the market price
Yuri [45]
Equilibrium is the intersect of the two curves. The curves show you how much the producers supply and how much the consumers demand at each possible price. 

The demand curves shows that the higher the price is, the less the consumers demand. That's obvious—the consumer wants something, but not at any price. He's only willing to pay so much. If the price goes higher and higher, less and less people want to buy the good. 

The higher the price is, the more the producers can supply. This is because some producers are able to produce at lower costs; they're better and more efficient than other producers. Other producers, who produce at higher costs, would go bankrupt if they tried to produce at lower prices. But when the price goes up, even the worse producers, who have higher costs, are able to make profit. So, more producers supply to the market. 

What happens now, when the price gets lower than the equlibrium? As you can see from the chart, producers would supply less than consumers would be willing to consume at that particular price. There would be SHORTAGE. This happens when the goverment sets price ceilings (like on gas in the 30's). An opposite situation happens when there is price floor—for example minimum wage (because wages are prices too; prices of labor). In that case, there is surplus—in case of minimum wage that means surplus of labor (unemployment). 

But when the markets are free to set the price, they will quickly establish equlibrium again. The producers will see that there is a shortage. They'll realize they can set higher prices and make bigger profits. They can't set higher price than the equilibrium though, because there would be surplus and they would have their warehouses stuffed with goods noone wants to buy at that price. 

This is the Answer Am 100% sure.
