Answer:
56+6.23t≥175
Explanation:
t=number of tickets
Marty needs at least $175. He already has $56. He keeps selling tickets for $6.23 per ticket. He needs to get at least $175, but he could get more. So 56, the amount of money he already has, plus 6.23 times the amount of tickets he will sell has to equal or be higher than $175.
