FORMULA IS:15*D+.22*M WHERE D=NUMBER OF DAYS & M=NUMBER OF MILES.
THUS THE COST FOR 1 DAY RENTAL WITH 300 MILES IS:
15+.22*300=15+66=$81 ANSWER FOR 1 DAYS RENTAL WITH 300 MILES.
Answer by mathslover(157) (Show Source): You can put this solution on YOUR website!
Let "m" be the number of miles driven in day
Given Charges per mile = $.22
Charges for driving m miles = $(.22*m)
Total rental for the day is $(15 + .22m) where m is thenumber of miles driven in a day
Cost when 300 miles are driven in a day = $(15 + .22*300)
=$(15+ 66)
=$81
