1981 is the same as an orange in 2005‚ a computer is not – it’s harder to count up “quantity” in two different years. So‚ to get an idea of “quantity”‚ the best thing is to look at total expenditure and divide it by the price level. It’s simple to calculate real investment (a component of real GDP) in year 1‚ the base year: Yr. 1 Real Investment = (100 computers)*($1) + (106 trucks)*($1) = $206 Now‚ usual calculation of real investment in year 2 would take year 2 quantities and value them at base

Use the data given to calculate annual returns for Goodman‚ Landry‚ and the Market Index‚ and then calculate average annual returns for the two stocks and the index. (Hint: Remember‚ returns are calculated by subtracting the beginning price from the ending price to get the capital gain or loss‚ adding the dividend to the capital gain or loss‚ and then dividing the result by the beginning price. Assume that dividends are already included in the index. Also‚ you cannot calculate the rate of return for

wheat in Home is: D = 100 - 20P And the supply of wheat in Home is: S = 20 + 20P. Numerically calculate the demand equation for imported wheat in Home. Draw the corresponding curve. What is the price of wheat in Home if there is no trade with Foreign? b) Now add Foreign. The demand for wheat in Foreign is: D* = 80 – 20P‚ while the supply of wheat in Foreign equals S* = 40 + 20P. Numerically calculate the supply equation for wheat exported by Foreign. Draw in the corresponding curve in the figure

Name: Skill Sheet 17.3 Thin Lens Formula Here you will become familiar and practice with a mathematical formula called “the thin lens formula.” This formula gives scientists a way to calculate the location and the size of an image that is produced by a lens. 1. What is the thin lens formula? When you use the thin lens formula‚ you assume that the thickness of the lens is very small compared with the distance between the lens and the object or the image. The formula applies both to convex or converging
