To solve the question we use the compound formula given by:
A=P(1+r/100)^n
where:
A=future amount
P=principle
r=rate
n=time
From the question:
A=$35756, r=2.2%,t=35 years Thus plugging the values in the formula and solving for P we shall have:
35756=P(1+2.2/100)^35
35756=P(1.022)^35
thus
P=35756/(1.022)^35
P=$16,694.2755~$16,694.3
Therefore she needs $16, 694.3 in her account
