Write and equation ( and maybe solve) please!

At the Shine AutoWash, a car wash costs $8.00, and nearby gasoline is selling for $1.369 per litre. Terri has $49.75 to spend, and her car is so dirty she must have it washed. What is the maximum number of litres of gasoline that she can purchase?

49.75 - 8 = 41.75.  41.75 / 1.369 = 30.4967129.  Let's round it to 2 decimal points, which is 30.5.  The maximum number of litres of gasoline that Terri can purchase is 30.5.  If m= money, c= price of car wash and g= price of gasoline per litre, the equation is (m - c) / g.
