RT, I asked my 15 year old freshman son ( a math genius, gg) to do a quick calculation for me.
I told him the problem:
- Vivus has filled about 500,000
prescriptions so far in one year ( I rounded it off), 1997.
-each prescription has 6 intraurethral pellets and costs $120.
-the weekly refill rate is 7.4%.
-the past week 10,000 ( rounded off ) new scrips were written.
I asked him the question: How many new prescriptions will be filled at the end of 52 weeks from today? What is the formula?
He said:
First the formula:
I ( 1.074 )^52
where,
I = initial No. of prescriptions, times 1.074, to the power of 52.
So that plugging in the available data, he calculated:
500,000(1.074)^52 = 20473525.5707 new scrips in 1998, then
20,473,525.5707scrips x $120/script = $2,456,823,068.48 in sales
the first year.
Before anybody has a heart attack on this thread, let me just say that this are a 15 year old's calculations, ( GG ) and I invite corrections, especially from the more mathematically inclined members of this thread. Son will be back later tonight at which time ( or tomorrow ) I will ask him to review YOUR work,( gg ) and to comment,
