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
A coefficient is a number that goes in front of the variable, so -3 would go in front of m. A constant is just a number on it's own, so it would be +17
