Quiz – Chapter 17 – Solution 1. Rider Company sells a single product. The product has a selling price of $40 per unit and variable expenses of $15 per unit. The company’s fixed expenses total $30‚000 per year. The company’s break-even point in terms of total dollar sales is: A) $100‚000. B) $80‚000. C) $60‚000. D) $48‚000. The answer is d. CMR = (P-V)/P = ($40 - $15)/$40 = 62.5% Px = F/ (CMR) Px = $30‚000/.625 = $48‚000 Use the following to answer questions 2-3: Weiss Corporation produces two models

Variable costs are those costs that increase as the output the restaurant increases. As example‚ assume for the Teen Burger Direct Materials cost $1.50 per burger. A day with one thousand burgers sold would cost of $1500 dollars. In comparison‚ a day with two thousand burgers sold would cost $3000 dollars. While the cost per Teen Burger remains constant the total cost per day varies with the output each given day. Electricity costs would increase in the same fashion as each time a burger is cooked

Two-Variable Inequality (YOUR NAME HERE) MAT 221 (YOUR PROFESSOR ’S NAME HERE) February 10‚ 2014 Two-Variable Inequality We use inequalities when there is a range of possible answers for a situation. That’s what we are interested in when we study inequalities‚ possibilities. We can explore the possibilities of an inequality using a number line which is sufficient in simple situations‚ such as inequalities with just one variable. But in more complicated circumstances‚ like those with two variables

T-test for Two Independent Samples * This test is used when only two unrelated groups are being compared and the measurements are either interval or ratio. The two groups may or may not have the same number of samples. * The t-test for two independent groups involves testing whether or not there is a significant difference between the population means of the two groups. Consider a study wherein the effectiveness of banana leaves as an organic wrapper was compared to that of aluminum foil

a) Identify the major variables that you controlled or measured in this investigation. What type of relationship do these variables have with each other? The variable that we manipulated was the fuel to oxygen ratio and the variable that we observed was how efficiently the fuel burned in each of the mixtures. The efficiency of the combustion depended on the fuel to oxygen ratio. If mixture was fuel lean the combustion reaction would produce less soot and smoke. If the mixture was fuel rich‚ an incomplete
