The multiplier is 54,000 / (1+3+8) = 54,000 / 12 = $4500
so 1 person got 1* 4500 = $4500
another got 4500 * 3 = $13,500
another got 4500 * 8 = $36,000
First find how many students are sick the second year:

Answer:
Step-by-step explanation: emma's amount be X . justin has $7.50+x because he has $7.50 more than emma.Since emma has 7.50+x-$12.to get everyones amount add what they have together which is=$7.50+x+$7.50+x-12 which in total is $63.00.after the calculations you get x=30.now distribute the x equally. so justin has $7.50+30=37.50.we also distribute it with emma's which is 7.50+30-12=25.5.
justin=$37.50
Emma=$25.50
to be sure add 37.50+25.50=$63
