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.

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
