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

:
