E22-5, Compute contribution margin, break-even point, and margin of safety. In the month of June, Bonita Beauty Salon gave 2,700 haircuts, shampoos, and permanents at an average price of $30 During the month, fixed costs were $18,000 and variable costs were 70% of sales. Instructions: (a)(1) Determine the contribution margin in dollars. Total Sales $81,000 Variable Cost 56,700 Contribution margin in dollars $24,300 (a)(2) Determine the contribution margin as a ratio. Contribution margin in dollars Total Haircuts Given Per unit Contribution margin (b)(1) Using the contribution margin technique, compute the breakeven point in dollars. Breakeven sales (in dollars): Amount = Formula Percentage (b)(2) Using the contribution margin technique, compute the breakeven point in units. Breakeven sales (in units): Amount = Formula units Amount (c)(1) Compute the margin of safety in dollars. Margin of safety (in dollars): Amount – Amount = Formula (c)(2) Compute the margin of safety as a ratio. (Rounded to a whole percentage.) Margin of safety (ratio): Amount ÷ Amount = Formula

What are three ways that agriculture have affected the development and success of Africa?

An astronomer makes n measurements of the distance between Jupiter and a particular one of its moons. Experience with the instruments used leads her to believe that for the proper units the measurements will be normally distributed with mean d, the true distance, and variance 16. She performs a series of n measurements. Let An = (X1 + X2 +… + Xn)/n be the average of these measurements. (a)Show that P{An -8/n^.5<=d<=An + 5/n^.5} Approx equals .95
