Cindy has $75. She goes to the store and buys a set of markers for $6, a box of pencils for $12, and 4 notebooks. The notebooks
all cost the same. Cindy has $39 left when she leaves the store. Part A. Write an equation to determine the price of one notebook. Let n represent the cost of the notebook.
A: We want to take away all the useless numbers that don’t relate to the notebook first, and subtract them. 75 - 6 = 69 69 - 12 = 57 There, now we have to subtract the amount of money she has when she leaves from the total amount spent right now. 57 - 39 = 18 To get the amount spent on all four notebooks, all you need to do is divide by 4 18 / 4 = $4.50 And that’s your answer!
