Answer:

72+4t> 400,

t >82.

Step-by-step explanation:

Let t be the number of tickets the committee sold.  If Middle School earns  $4 for each ticket sold to the Spring Fling dance, then they earn $4t for t tickets sold.

If  Middle School earns $72 from a bake sale and earns $4t from selling t tickets, then they earn $(72+4t) in total.  

The dance will cost $400, so

72 + 4t > 400,

4t > 400 - 72,

4t > 328,

t > 82.
