Assume a demand equation for good 'x': upper q equals 9 minus 0.1 p minus p subscript y baseline plus 0.01 p subscript z baseline plus 0.0005 upper y; where p = own price of the good py = price of a related good = $3 q = quantity demanded pz = price of a different related good = $200 y = consumer income = $4,000/mo. the quantity demanded as a function of the price can be written: q = nothing if the price of this good 'x' is equal to $42 per unit, what would be the quantity demanded? nothing units. (enter your response rounded to one decimal place)

Anew firm is developing its business plan. it will require $615,000 of assets, and it projects $450,000 of sales and $355,000 of operating costs for the first year. management is reasonably sure of these numbers because of contracts with its customers and suppliers. it can borrow at a rate of 7.5%, but the bank requires it to have a tie of at least 4.0, and if the tie falls below this level the bank will call in the loan and the firm will go bankrupt. what is the maximum debt ratio the firm can use? (hint: find the maximum dollars of interest, then the debt that produces that interest, and then the related debt ratio.)a. 41.94%b. 44.15%c. 46.47%d. 48.92%e. 51.49%
