Answer 2

The charges are :

$17 fixed charge plus an additional $6 per every hour of renting

Taking h as the number of hours taken for renting the bike, then an equation for total cost of renting the bike will be,

c=$17 + $6h -------- where c is the total cost

Given that the cost Tim paid is $59 then use the equation to get the hours he check out as;

c=$17+ $6h

$59 = $17 + $6h

collect like terms as;

$59 - $ 17 = $6h

$ 42 = $ 6h

42 = 6h

42/6 = h

7 = h

So the number of hours Tim check out the bike is 7 hours.
