Final answer:
Mr. Oliveros spends $35.00 on student tickets. Since each student ticket costs $2.50, he can buy 14 student tickets.
Step-by-step explanation:
To find out the number of student tickets Mr. Oliveros buys, we need to calculate how much he spends on student tickets first. This is done by subtracting the cost of his ticket from the total amount spent, which is $45.00 - $10.00, resulting in $35.00 spent on student tickets. To find the number of tickets, we can then divide this amount by the price of each student ticket. Therefore, the calculation would be $35.00 ÷ $2.50. As a result, Mr. Oliveros buys 14 student tickets.
