Answer:
[tex]72+4t>400,[/tex]
[tex]t>82.[/tex]
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
[tex]72+4t>400,\\ \\4t>400-72,\\ \\4t>328,\\ \\t>82.[/tex]
