Last year’s freshman class at Big State University totaled 5,324 students. Of those, 1,253 received a merit scholarship to help offset tuition costs their freshman year (although the amount varied per student). The amount a student received was N($3,450, $470). If the cost of full tuition was $4,050 last year, what percentage of students who received a merit scholarship did not receive enough to cover full tuition? (Round your answer to the nearest whole percent.)
