A logic problem A new drug is launched. First week 100 new scripts are written. Each week 50 few scripts are written until it levels off at 50 new scripts. A script has enough units to last an average of 4 weeks. Half of the people using the drug continue to renew it. What do script numbers look like? I get the following : new refill Week 1 100 0 2 95 0 3 90 0 4 85 0 5 80 50 6 75 97.5 7 70 137.5 8 65 180 9 60 220 10 55 257.5 11 50 292.5 12 50 325 13 50 355 14 50 382.5 15 50 407.5 16 50 432.5 I understand why Muse new scripts are 2200 and that number doesn't bother me. We should be growing at a rate of 2200/0.6 or 3500 new customers a week. It's the refills, where are the refills????
