Answer:
Original price= $3,200
Step-by-step explanation:
Giving the following information:
Purchase price= $2,816
Discount rate= 12% = 0.12
<u>To calculate the original price, we need to use the following formula:</u>
Original price= purchase price / (1 - discount rate)
Original price= 2,816 / 0.88
Original price= $3,200
-4 is also a geometric mean
if we consider a(first element in series)=1 and r(common ratio)=-4 then the series would be
1,-4,16,-64,256,…..,a(-4)^(n-1 )
where n is nth term
from this -4 would be the geometric mean if we consider -4 as common ratio .
If we consider 4 as common ratio then geometric mean should be 4
so you should mention whether common ratio >0 or not (r>0 or not) .
[without ‘r’ value you can’t solve the question but in general most of the teachers will consider r>0.]
So, -4 won’t be geometric mean of 1 & 16
