Answer:

168 months

Step-by-step explanation:

Given data

Price= $800

Rate of decrease= 7%

New price= $300

Applying the compound interest formula for time t

t= ln(A/P)/r

t= ln(300/800)/0.07

t= ln(0.375)/0.07

t= 0.9808/0.07

t= 14.011 years

Hence in months

=14.011*12

= 168.1

=168 months
