Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…

Textbook Question

Chapter 2.B, Problem 79E

Fertilizing Winter Wheat. Guidelines for the amount of supplementary nitrogen needed to grow winter wheat depend on the amount of nitrogen in the soil (as determined by a soil test), the price of fertilizer, and the price of wheat at harvest. Suppose the soil on a particular farm has a nitrogen content of 2 ppm (parts per million) and 50 acres will be planted in wheat. Consider two pricing scenarios.

• Case A: The price of fertilizer is $0.25/lb, the price of wheat is $3.50/bushel, and the expected yield is 60 bushels/acre.

• Case B: The price of fertilizer is $0.50/1b, the price of wheat is $4.50, and the expected yield is 50 bushels/acre.

In Case A, the guidelines recommend adding 100 pounds of nitrogen per acre, and, in Case B, 70 lbs of nitrogen should be added per acre.

Assuming all other factors are equal, compute and compare the net profit (income minus expenses) for the two scenarios.

2. Cost of a Hybrid Vehicle You may have wondered what the break-even point is for purchasing a hybrid vehicle if you paid in cash (no interest). Below is data for two models of Honda Civic bases on $4.00 per gallon gas prices. Base Price ($) Cost/Mile ($) Civic Hybrid 22,600 $0.095 Civic Ex $18,710 240.14 Source greencar.com a. Find the cost function for each car, as a function of miles driven x. b. Determine the break-even miles. This represents the number of miles you would need to drive the hybrid before it becomes the cheaper alternative.

INTERPRET THE RESULT1) Check for consistency in the relationship between quantity demand and the three explanatory variables as postulated in demand theory by indicating the change in the quantity demanded of the commodity for each unit change in the explanatory variables. 2)Find and interpret the adjusted and the unadjusted coefficient of determination.

Motorking Corporation, a market leader in the production of specialized engine additives, is considering introducing a new "gas extender" product. This product is added to an automobile’s gasoline to extend mileage and reduce exhaust emissions. Motorking's manufacturing facility can produce 50,000 cases of the new product per year with a set-up cost of $100,000. The average variable cost per case would be $5. Large orders, (i.e., above 50,000 cases) will be subcontracted to a local refining company. Motorking has signed a secrecy agreement with the vendor that guards the basic process. The variable cost per case, if the new product is produced outside, is $9. Whether the product is manufactured by Motorking or by the vendor, there is a $12 per case cost for marketing and overhead. Motorking's production manager is considering three production levels for the new product: 50,000 cases, 75,000 cases, and 100,000 cases. The level of sales will depend on the state of the economy. Sales…
