Question 915052: Note: You may be able to do some of these problems without writing an inequality for it. But, since we are learning how to translate sentences to equations and inequalities, we expect you to demonstrate your ability to do this, and therefore that you will define a variable and write an inequality, then solve it, and graph if required.
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?

You can put this solution on YOUR website!
Let +x+ = maximum liters of gasoline
+x+%3C+=+%28+49.75+-+8+%29+%2F+1.369+
+x+%3C+=+41.75+%2F+1.369+
+x+%3C+=+30.497+
The maximum number of liters is
about 30.5
