Lasami Abdullah FIN3403 Homework Chapter 3 Chapter 3 #1-6 & #8-11 1. Division A profit margin = Net Income/Sales = $100‚000/$2‚000‚000 = .0500 = 5% Division B profit margin = Net Income/Sales = $25‚000/$300‚000 = .0833 = 8.3% Based on the return on sales‚ Division B is superior even though they didn’t sell as much in dollars as Division A‚ their profit margin is higher. 2. Database Systems Net Income = Sales * Profit Margin = $1‚200‚000 * 0.06 = $72‚000 Return on Assets (Investment)

Abstract This laboratory involved utilizing equipment to dilute a sugar water solution. It also created solutions containing varying levels of concentrations and densities. Equations were used to figure the molecular weight of the sugar‚ and the number of moles of sugar in the volumetric flask. There was also an equation to figure the Molarity‚ as well. As a result of the experiment‚ I now have a better understanding of the density of a concentration‚ and what Molarity is . Observations Data

identify an unknown solution‚ based on the reactions (i.e. color changes) of known solutions with indicator solutions. These known solutions contained different types of macromolecules. Each type of micromolecule reacted with at least one indicator solution in a unique way‚ which allowed us to identify the macromolecule based upon the presence or absence of a color change. Water was also used as a control solution‚ as it showed a negative reaction with the indicator solutions. Seven sets of three

Solutions for controlling inflation and stabilizing the macroeconomic in Vietnam In short term‚ firstly‚ the government should manage the monetary policy as well as the tight fiscal policy in order to reduce aggregate demand of the economy‚ stabilizing the value of Vietnam dong. In terms of the monetary policy‚ it is necessary to coordinate reasonably the amount of credit money‚ avoiding the situation that the amount of credit money increases suddenly at the end of a year. In terms of the fiscal

1. Solution is a homogeneous mixture composed of only one phase. In such a mixture‚ a solute is a substance dissolved in another substance‚ known as a solvent. Suspension is a heterogeneous mixture in which the particles are large enough to be seen by a microscope or the unaided eye and eventually‚ they settle out of the mixture. A colloid is a substance microscopically dispersed throughout another substance. Unlike colloids‚ suspensions will eventually settle. The suspended particles are visible
