27. Suppose A D = E, that N = 21,000, E/A = .75 and N/E = .40. Compute D/A.

28. Assume that S/A = 5.2, D/A = .15, N/E = .75 and A = D + E. Solve for N/S.

For each of the algebra problems below, round your answer to 2 decimal places and record your answer on D2L without (if applicable) a comma. Thus, enter 3.24765 as 3.25 or .18763 as 0.19 or 3,214.842876 as 3214.85. 23. Given the following ratio relationships: D/A = 0.62 N/E = 0.26 D+ E = A What is N/A? 24. Given the following ratio relationships: D/A = 0.38 A-D=E What is D/E? 25. Given the following ratio relationships: D/A = 0.70 N/A= .18 A=D+E . What is N/E? 4
