Question

8- What is A if P = [A × (1+R)^L] + [B × (1+R)^M] and P = 31,244, B = 5,963, R = 0.1337, L = 3, and M = 9? Round answer to nearest whole number.

10- What is C if X = (A + B – C) / C and X = 0.3427, A = 447, and B = 8,921? Round answer to nearest whole number.

11- What is D if D = A – B – C and A = 0, B = -8,503, and C = 5,478? Round answer to nearest whole number.

12- What is M if R = F + ((B × (M – F))) and R = 0.194, B = 1.7, and F = 0.0692? Answer as a rate in decimal format so that 12.34% would be entered as .1234 and 0.98% would be entered as .0098.

Answer 1

8.

P = [A × (1+R)L] + [B × (1+R)M]

31244 = [A × (1+0.1337)3] + [5963× (1+0.1337)9]

31244 = [A × 3.4011 ] + [ 5963 * 10.2033 ]

31244 = 3.4011 A + 60842.2779

A = (31244 - 60842.2779 ) / 3.4011

= -8702.56

ANS= -8703

10.

X = (A + B – C) / C

0.3427 = ( 447 + 8921 - C) / C

0.3427 C = 447 + 8921 -C

1.3427C = 9368

C= 9368 / 1.3427

= 6976.987

ANS= 6977

11

D = A -B -C

D = 0 - ( -8503) - 5478

= 8503 -5478

= 3025

12

R = F + ((B × (M – F)))

0.194 = 0.0692 + ((1.7 * ( M - 0.0692)))

0.194 - 0.0692 = 1.7 * ( M - 0.0692)

0.1248 / 1.7 = M - 0.0692

M = 0.1426

ANS : 14.26%
