Mrs. Drew’s class is doing a survey of the 8 th grade students. They are collecting data of each student’s arrival time at schoo
l and each student’s assigned lunch time. When arrival time is the independent variable and lunch time is the dependent variable, is the relation a function or not a function?
The wholesale price = $112 Markup percentage = 40% or 0.40 So, the expression that will give the retail price of the item = 112 + 0.40 (112) Retail price = purchase/wholesale price plus markup
