3. Two brothers decide to invest in a vacant lot which cost $51 000. The first brother contributes $1000 more than one-quarter of what the second brother contributes. How much does each brother contribute?a. B1 = 11000, B2 = 40000b. B1 = 40000, B2 = 11000c. B1 = 12500, B2 = 38500d. B1 = 50000, B2 = 10000e. B1 = 1000, B2 = 50000 4. Solve for x and y: 4x + 9y = 72, 6x + 15y = 90a. x = 45, y = -12b. x = -45, y = 12c. x = 45, y = 12d. x = -45, y = -12e. x = -45, y = -15

x + 2 = 2x - 19 Subtract Response area from both sides and you'll get... 3x + 2 = -19 Subtract Response area from both sides and you'll get... 3x = -21 Response area 3 on both sides and you'll get... x = Response area
Each morning during rush hour, 10,000 people want to travel from New Jersey to New York City. If a person takes the commuter train, the trip lasts 40 minutes. If x thousand people per morningdrive to New York, it takes 20 + 5x minutes to make the trip. This problem illustrates a basic fact of life: If people make their decisions individually, they will cause more congestion than is actually necessary.a. Show that if people make their decisions individually, an average of 4000 people will travel by road from New Jersey to New York. Here you should assume that people will divide up betweenthe trains and roads in a way that makes the average travel time by road equal to the travel time by train. When this “equilibrium” occurs, nobody has an incentive to switch from the road to thetrain or vice versa.b. Show that the average travel time per person is minimized if 2000 people travel by road.
