0 < x < yRx + y < 0Quantity Ax - yQuantity BR
Answer(s): A
We are given:1. 0 < x < y2. Rx + y < 0From (2):Since 0 < x < y, the ratio y/x > 1. Therefore:So, R is less than 1.Now compare:Quantity A = x - yQuantity B = RBecause x < y x - y < 0But since y > x > 0More simply, using an example that fits all conditions:If x = 1, y = 2, then x - y = -1Condition R < -y/x = -2 forces R < -2So, x - y = -1 is greater than any such R.x - y > RQuantity A is greater.
If 1.375y = 1, what is the value of y, expressed as a fraction?
Answer(s): C
1.375 = , so y = 1 ÷ =
If Transit Company T will run 60 trains per day, then the projected annual revenue is approximately what percent greater than the projected annual cost?
Answer(s): E
At 60 trains per day the solid (revenue) curve is a little above the 200-million line, while the dashed (cost) curve is a little below the 160-million line.Projected revenue $210 millionProjected cost $160 millionDifference = 210 160 = 50 million.Thus the revenue is about 30 percent greater than the cost.
If Transit Company T will run 40 trains per day for a year, approximately what is the projected average revenue per day?
Answer(s): B
At 40 trains per day, the solid "Revenue" curve is a little below the midpoint between $125 million and $150 million on the vertical scale - about $140 million a year.The closest choice is $360,000.
Transit Company T's projected annual cost consists of staffing costs, fuel costs, and equipment costs in the ratio of 1 to 2 to 5.If the company will run 50 trains per day, approximately what is the projected annual cost for fuel?
At 50 trains per day, read the cost on the dashed curve:The cost curve at 50 trains per day is a little above $125 million and below $150 million.The best estimate from the graph is about $130 million.The cost ratio is:Staffing : Fuel : Equipment = 1 : 2 : 5Total parts = 1 + 2 + 5 = 8Fuel corresponds to 2 parts, so fuel cost is 2/8= 1/4 of the total cost.Compute fuel cost:1/4 × 130 million 32.5 millionClosest answer: $32 million
