 Question 131728: The word problem is this: Suzanne had 9 CDs. She decided to add CDs to her collection at the same rate each week. After 2 weeks, she had 15 CDs.In how many weeks did she have 27 CDs? How many CDs did she have after 8 weeks? MY daughter plotted it out on a graph and came up with (0,9) (2,15) (6,27) and (8,33) Which would mean that she had 27 CDs in 6 weeks and 33 CDs in 8 weeks. And then she was asked to write an equation for this word problem Her answer was : Y= 9+2X Could you please tell me if this is correct? Thank You Mother lost in Algebra Click here to see answer by josmiceli(9664)
