Question 342679
tom's bike shop rents bikes for $0.30 a mile and an initial $10.00 fee. joe's bike shop rents bikes for $0.50 a mile and an initial fee of $6.00. at what mileage would the two shops cost the same? what would that cost be?


let the number of miles be x
TOM 
0.3x++10
JOE
0.5x+6
..
0.3x+10=0.5x+6
-0.3x
0.3x-0.3x+10=0.5x-0.3x+6
10=0.2x+6
-6
10-6=0.2x
4=0.2x
x=4/0.2
= 20 miles.
At 20 miles both will cost the same
