Example. — What is the amount of an annuity of $35 at the
end of 17 years at 5 per cent interest?
From Table 26 the amount of an annuity of $1 for 17 years at
5 per cent is found to be $25.84037, consequently the amount of
an annuity of $35 will be
35 X 25.84037 = $904.41.
Or from Table 22 the amount of $1 at 5 per cent compound
interest for 17 years is found to be 2.292018, therefore, according
to equation (22a),
vo 2.202018 — 1
A" = Oe 25.84036
and the amount of the annuity of $35 will be
35 X 25.84036 = $904.41.
When the annuity is applied at the beginning instead of at the
end of the year and the amount thereof is designated by A’,
then:
