Margaret is certain that every time she parks in the municipal garage it costs her at least $ 2.50. if the garage charges 40cents plus 30cents for each half hour, how long is margaret's car parked?

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.
