First find the maturity value of the note, 15000+[15000*0.11*120/360]=15,550then find the term of discount,120-[27+31+11]=51daysthen multiply the maturity value by discount rate and the term of discount, 15,550*0.09*51/360=198.26then get the difference between the maturity value and the discount,15550-198.26=15,351,74So,the proceeds is 15,351.74 which is #2
For every 1/4 metric ton it takes 1/8 hours then multipling by 8 to make the hours =1 for every 2 metric tons it take 1 hour so the quotient is 2 metric tons per 1 hour
