- The monthly cost for household water is computed based on the amount of water used in thousand gallons: kgals. A local water company charges a monthly service fee of $20 and then charges $1.25 for each kgal of water used up to 10 kgals. To discourage excessive use, each kgal of water beyond 10 kgals is charged at rate of $2.75 per kgal. a) Write a piecewise defined function for the monthly cost of household water, C, in terms of the amount of water used, x kgal. b) Using your model, determine the monthly water bill if 9 kgals of water is used by a household. c) Using your model, determine the monthly water bill if 14 kgals of water is used by a household. d) If a monthly water bill was $75, how much water did this household use (according to your model)? Be precise! Your answer should be accurate to 3 decimal places.arrow_forwardThe Ministry of Finance in Paradise Island determined that the import demand for Cognac is related to a proposed luxury tax using the formula: C(x) = √10000 − 40x − 0.02x2 where C(x) measures the percentage of normal consumption of Cognac when a luxury tax of x% is imposed on it. (i) Write a function for the rate of change import demand with respect to changes in the luxury tax. (ii) Find the rate of change of C(x) for a 10% tax. (iii) Find the rate of change of C(x) for a 100% tax.arrow_forwardOn a certain route, an airline carries 6000 passengers per month, each paying $200.
