Final answer:
The equation that can be used to find the number of tickets each team needs to sell so that the total amount raised is the same for both teams is option B: 3.50t + 490 = 4t + 300.
Step-by-step explanation:
The equation that can be used to find the number of tickets each team needs to sell so that the total amount raised is the same for both teams is option B. 3.50t + 490 = 4t + 300. We can set up the equation by equating the total amount raised by the Tigers ($3.50 multiplied by the number of tickets they sell plus the $490 they have already raised) to the total amount raised by the Lions ($4.00 multiplied by the number of tickets they sell plus the $300 they have already raised). Simplifying the equation, we have 3.50t + 490 = 4t + 300. Now we can solve for t, which represents the number of tickets each team needs to sell.
