Because each student ticket costs $2 and each adult ticket costs $3, the total amount, in dollars, that Chris spends on x student tickets and 1 adult ticket is 2(x)+3(1). Because Chris spends at least $11 but no more than $14 on the tickets, one can write the compound in equality 2x+3≥11 and 2x+3≤14. Subtracting 3 from each side of both inequalities and then dividing each side of both inequalities by 2 yields x≥4 and x≤5.5. Thus, the value of x must be an integer that is both greater than or equal to 4 and less than or equal to 5.5 Therefore, x=4 or x=5. Either 4 or 5 may be gridded as the correct answer.
