- 7/20 + -2/5 ? 16 / 20, I'm pretty sure
Adults = x
Students = y = x + 40. 40 more student than adult
Adult = $8, Student = $6
Total for Adults = 8*x = 8x
<span>Total for students = 6*y = 6y
</span>
Total = $1920
8x + 6y = 1920
Hence system of equations are:
<span>y = x + 40
</span>
<span>8x + 6y = 1920</span>
