Last year's freshman class at Big State University totaled 5,324 students. Of those, 1,254 received a merit scholarship to help offset tuition costs their freshman year (although the amount varied per student). The amount a student received was ($3,456,$478). If the cost of tuition was $4,200 last year, what percentage of students did receive enough to cover their full tuition?

Ответ:
RT = 20
Step-by-step explanation:
Since Y is the midpoint of RT , then
RY = YT , that is
3x - 2 = 8x - 22 ( subtract 8x from both sides )
- 5x - 2 = - 22 ( add 2 to both sides )
- 5x = - 20 ( divide both sides by - 5 )
x = 4
Then
RT = RY + YT = 3x - 2 + 8x - 22 = 11x - 24 , so
RT = 11(4) - 24 = 44 - 24 = 20
