Dr Baber wants to take her favorite Algebra 3/4 class to lunch at the Taco Stand (of course it's your class.) She has $120 from the Franklin Boosters. What are some of the
combinations of tacos and nachos she can get if nachos are $4.50 and tacos are $1.75?
She wants to have the smallest possible change back.
What is the inequality equation you need to use to find your answers?
