Question

5) What is C if X = (A + B – C) / C and X = 0.3189, A = 362, and B = 7,239? Round answer to nearest whole number. answer C = ___

6) What is D if D = A – B – C and A = 0, B = -5,079, and C = 8,856? Round answer to nearest whole number. answer D = ___

7) What is M if R = F + ((B × (M – F))) and R = 0.1397, B = 1.15, and F = 0.0428? 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 M = ___

Answer 1

5.

X = (A + B – C) / C

0.3189 = (362 + 7,239 – C) / C

0.3189C = 7,601 – C

C + 0.3189C = 7,601

1.3189C = 7,601

C = 7,601 / 1.3189

C = 5,763

Value of C is 5,763.

6.

D = A – B – C

D = 0 – (–5,079) – 8,856

D = 5,079 – 8,856

D = –3,777

Value of D is –3,777.

7.

R = F + (B × (M – F))

0.1397 = 0.0428 + (1.15 × (M – 0.0428))

0.1397 - 0.0428 = 1.15 × (M – 0.0428)

0.0969 = 1.15 × (M – 0.0428)

(M – 0.0428) = 0.0969 / 1.15

(M – 0.0428) = 0.0843

M = 0.0843 + 0.0428

M = 0.1271

Value of M is 0.1271.
