original principal. Round to the nearest dollar. (Hint:Use the model and substitute for A.) Select one:a. \$1,176b. \$9,379c. \$2,555d. \$8,000The correct answer is: \$8,000
Question 11Incorrect0.00 points out of 8.75Solve the system by using any method. If a systemdoes not have one unique solution, state whetherthe system is inconsistent or whether the equationsare dependent. 6x= - 5 0.24x- 0.01y= -0.2
Question 12Correct8.75 points out of 8.75Solve the system by substitution. 9x- 5y= 16 y= - x+ 6
Question 13Correct8.75 points out of 8.75Solve the problem. In an open market, the price of an item is dependent onthe demand by consumers and the supply offered byproducers. Competition between buyers and sellerssteers the price toward an equilibrium price——that is,the price where supply equals demand. The number ofitems offered and sold at the equilibrium price is theequilibrium quantity. The price p (in \$) of a cookbook is determined by thenumber of cookbooks x demanded by consumers andsupplied by the publisher. Supply: p =0.003Demand: p =-0.005x +80 a. Solve the system of equations defined by the supplyand demand models. b. What is the equilibrium price? c. What is the equilibrium quantity?Select one:x
Question 14Incorrect0.00 points out of 8.75Solve the system. If a system has one uniquesolution, write the solution set. Otherwise,determine the number of solutions to the system,and determine whether the system is inconsistent,or the equations are dependent. Select one:a. No solution; inconsistentb. {(-1, 157, -30)}c. {(2, -23, 6)}d.
