Final answer:
To cover the production costs of $1750 with student tickets priced at $5, North High School would need to sell 350 student tickets.
Step-by-step explanation:
The question asks to calculate how many student tickets must be sold at $5 each to cover the production costs of $1750 for North High School's spring musical. To determine this, divide the total production costs by the price of one student ticket: $1750 / $5 = 350. Therefore, the school must sell 350 student tickets to cover the production costs without considering adult tickets or total seating capacity.
