answer:
the value when it was purchased was $425,000
step-by-step explanation:
the formula for calculating the percent change over time is:
p
=
n
−
o
o
⋅
100
where
p
is the percent change,
n
is the new value and
o
is the old value. in this problem we are given
p
(36) and the new value ($578,000). we can substitute this into the formula and solve for
o
:

=
578000
