Use the data set to choose the two measures that are equivalent. 4,5,6,7,8

median

There us no mode.

you have 6 cupcakes

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.
