(a)(i) A = 750 + (750*.09*8) = ?
(b) A = P(1+rt)
A/P = 1 + rt
A/P - 1 = rt
(A/P-1)/r = t
for he formula A=P+Prt, find the value of
(a). (i) A when P = 750. r=0.09 and t=8
(ii) P when A=720.r=0.12 and t=5
(b) make t the subject of the formula
2 answers
(a). (i) A = P + Prt
A = 750 + (750*0.09*8)
=750 + 540 =1290
(ii) A = 720 + (720*0.12*5)
=432
=720 + 432 =1152
(b). A = P + Prt
A -P = Prt ...Divide both sides by Pr...
(A-P) / Pr = t
A = 750 + (750*0.09*8)
=750 + 540 =1290
(ii) A = 720 + (720*0.12*5)
=432
=720 + 432 =1152
(b). A = P + Prt
A -P = Prt ...Divide both sides by Pr...
(A-P) / Pr = t
