I have ten assignment questions but I need help figuring out question 3, 5, 6

For these two problems, I had trouble figuring out what to do: For these problems I wanted a double check to make sure I did them right. For this I did: iday = 365 1.0401 but the 365 is like this 3 3 F 2 + L Then Z = =3 4 iday 3 ( 36.00 )( 13700 ) /( 4.0001074) 2 Z = 298,135.45 My Answer = 298,135.45 Iday = 365 1.0471 3 Z= 3 ( 32.50 ) ( 13000 ) = .0001258 2 4.0001258 +255,000 = 286,992.65 H = 3(286,992.6)-2(255,000) = 350,977.95 My Answer = 350,977.95 = .0001074 + 262,000 C= C= 2TF /i 2 ( 5.14 M ) ( 271 ) /.039 C = 267,269.19 My Answer = 267,269.19 My issue with this is how do I solve for i? I get the first part PMTn = PV * [i/1-1/(1+i)^n] PMTn = 290,000 * [.098/1-1/(1+.098)^4] PMT = 91090.76 This is the part I don't know what to do: 91090.76 = 299500 * [i/1-(1/1-i)^n] I=? Iday = 365 1.0341 3 Z= ( 3 ) ( 310 ) ( 3100 ) 4.0000916 = .0000916 2 +36000 = 65001.27 H = 3(65001.27) - 2(36000) H = 123003.81 My Answer = 123003.81 Necessary increase in assets = A/So * s = 617000/6500000 * (7.5M-6.5M) = 950,000 Spontaneous Increase in liabilities = L/So * s = 1914250/6500000 * (7.5M-6.5M) = 294,500 Projected Increase in retained earnings = M*S1*RR = .25 * 7.5M * .20 = 375,000 AFN = 950,000-294,500-375,000 AFN = 280,500 (my answer) For this I did t = 1+2+3+4+5 = 15 Y = 2.6+3.66+4.34+4.95+5.66 = 21.21 tY = 2.6+7.32+13.02+19.8+28.3 = 71.04 (tY I did 2.6*1, 3.66*2, 4.34*3, 4.95*4, 5.66*5) t^2 = 1+4+9+16+25 = 55 b = n * ty - (tot Y*tot t) / n *t^2 - (t)^2 b = (5*71.04) - (21.21)(15) / (5 * 55) - (15^2) b = .741 a = y / n - b(t) a = 21.21/5 - (.741)(15/5) a = 2.019 Y = 2.019 - .741(6) Y = -2.427 (my answer) Necessary increase in current assets = A/So * s = 1736000/6200000 *(8.2M-6.2M) = 560000 Necessary increase in fixed assets = 4216000/6200000 *(8.2M-6.2M) = 1,360,000, but because the problem states are added in 1M increments this will go up to 2M Spontaneous Increase in Liabilities = L/So * s = 1798000/6200000 *(8.2M-6.2M) = 580000 Projected increase in retained earnings = M * S * RR = .25*8.2M*.30 = 615000 So Additional funds needed = 560000+2M-580000-615000 AFN = 1,365,000 (my answer)
