40. Given the following ratio relationships: ● S/A = 7.6 ● N/S= .08 ● D/A = .55 ● A =D + E What is N/A? (Record your answer to a percent, rounded to 1 decimal place) 41. Suppose A - D = E, that N = 62,000, E/A = .565 and N/E = .40. Compute D/A (record your answer to a percent, rounded to 1 decimal place). 42. Assume that S/A = 2.5, D/A = .15, N/E = .75 and A = D + E. Solve for N/S (Record your answer to a percent, rounded to 1 decimal place). 43. Given the following equations: ● 4x + y = 12 ● 8x - 4y = 15 Solve for y. (Record your answer rounded to 2 decimal places; for example, record 18.3498 as 18.35). 44. Referring back to the prior problem, what is x? (Record your answer rounded to 2 decimal places; for example, record 18.3498 as 18.35). 45. Alex and Sam each build tables. Together they make 34 tables in 12 days. Alex working alone can make 46 tables in 30 days. How many days would it take Sam working alone to make 46 tables? (Record your answer in days rounded to one decimal place. For example, if the answer you find is 4.2835 days, record 4.3). 46. Which of the following numbers is the smallest? a. -3/4 b. -3/2 C. -1 d. -2/3 e. -7/4 47. Solve the following: 7m +3mn, given that m = 8 and n = 14. 48. Alex broke open his piggy bank. He had 30 more dimes than nickels and 8 more quarters than nickels. The value of the quarters is exactly the me as the value of the sum of the dimes and nickels. How much total money does Alex have (in cents, assuming the quarters are worth 25 cents, dimes are worth 10 cents, and nickesl are worth 5 cents)? 49. You must have an average score of at least 80 to get a B- in a class that you are taking. The class has 5 exams (all equally weighted). On exams 1, 2, 3 and 4 you earned grade of 61, 70, 99 and 73, respectively. What is the minimum score that you must get on exam 5 t get a B- in the class? (Record your answer as a number rounded to one decimal place; for example, record 83.8924 as 83.9). 50. Ed invests $68,000 in certificates of deposit (i.e., CDs) paying 1.75%. How much additional money does he need to invest in stocks that are expected to generate a return of 11.8% so that the average return on all of Ed's investments is 7.5%? (Record your answer as a dollar amount rounded to 2 decimal places, but do not include the dollar sign or any commas in your answer on iCollege; for example, record $29,354.22895 as 29354.23).
