Explanation / Answer

ok first thing is to make the equation t (total cost of rental) d (days rented each day costs $12.50) m (miles each mile costs ($0.25) (* means multiply) t = ($12.50 * d) + ($0.25 * m) now substitute the values given in your problem that you know intothe formula above t = $46.00 d = 1 $46 = ($12.50 * 1) + ($0.25 * m) $46 = $12.50 + (0.25 * m)        now subtract $12.50 from each side $46 - $12.50 = $12.50-$12.50 + (0.25 * m) $33.50 = 0 + (0.25 * m) $33.50 = 0.25 * m    now divide each side by$0.25 $33.50/$0.25 = 0.25 * m/$0.25 134 = m m = 134 This mean that she drove 134 miles you can check this by (134 * 0.25) + $12.50 = $46.00 Hope this helps I tried to explain every step!
