The four-firm ratio is the concentration ratio between the total sales accumulated by the four largest industrial firms to the total sales of all firms present in an industry. This translates to the mathematical expression of
four-firm ratio = (total sales of four largest firms / total sales)
Since, we are given that all 10 firms have the same sales, we let the sales be equal to x.
total sales of four largest firms = 4x
total sales = 10x
The ratio is then,
four-firm ratio = 4/10
Converting this to percentage will yield us an answer of 40%.
IRR function for this problem is 7. 7% and invest in the project
<h3>What is
IRR function?</h3>
The Excel IRR function returns the internal rate of return (IRR) for a sequence of cash flows that occur at regular intervals. Determine the internal rate of return. Return was calculated as a percentage. =IRR (values, [guess])
IRR is the interest rate at which the sum of all cash flows equals zero, thus it is useful for comparing one investment to another. In the preceding example, if we substitute 8% with 13.92%, the NPV becomes 0, and your IRR becomes zero. As a result, IRR is defined as the discount rate at which a project's NPV becomes zero.

Answer:
The correct word for the blank space is: lower; buyers to offer higher prices.
Explanation:
In a market driven by supply and demand laws, shortages are caused because of excess in demand as a result of lower prices. Thus, that price is lower than the equilibrium price. Besides, if there is a need to push that price to its equilibrium level, sellers will have to increase the price implying buyers will have to offer higher prices.
