 View Single Post 07-27-2007 #2 Mr. Scientist Guest   Posts: n/a It seems like you are asking alot of word problem questions. Try to assign variables to each item in the question that you need to figure out. Then make an equation with those variables and the numbers from the problem.I'll help with the first one."Jay's salary is 2/3 of his wife's salary."so...Wife's salary = x (just choose a variable)Jay's salary = 2/3 * x or just 2/3 x (2/3 of his wife's)"In Jan., wen they both get \$2000 raises, their combined income will be \$49000."Jay's (2/3x) + \$2000 + wife's (x) + \$2000 = \$490002/3x + 2000 + x + 2000 = 49000x + 2/3x + 4000 = 490005/3x = 450005x = 135000 (multiply both sides by 3)x = 27000 (divide both sides by 5)What are their current incomes?*tricky question, they have NOT gotten their Jan. raises yet.*Wife's salary = x = \$27000Jay's salary = 2/3x = \$18000 (27000 x 2/3)So just read your questions, and try to make an equation out of them.Good luck!
