A truck rental company offers two plans. One rental plan is $78 per day and $.12 per mile driven. Te other truck plan offers no daily fee but it is $.36 per mile driven. Determine the number of miles that must be driven in one day for the cost to be the same.

let the number of miles be m
.36m = .12m + 78
.24m = 78
m = 78/.24 = 325
