Question

PLEASE SHOW THE WORK! THANKS!

The number of retail drug prescriptions (in millions) can be approximated by y 86.83x 2941.19, where x = 0 corresponds to the year 2000. Find the approximate number of prescriptions in the following years. (a) 2004 (b) 2006 (c) Assuming that this model remains accurate, in what year will the number of prescriptions be 4,250,000,000? (a) In 2004, the approximate number of prescriptions was million. (Type an integer or decimal rounded to two decimal places as needed.) (b) In 2006, the approximate number of prescriptions was million. (Type an integer or decimal rounded to two decimal places as needed.) (c) The number of prescriptions will be 4,250,000,000 in the year

Explanation / Answer

a) In 2004, x = 4

Hence,

y = 86.83(4) + 2941.19

y = 3288.51

b) In 2006, x = 6

Hence,

y = 86.83(6) + 2941.19

y = 3462.17

c) Number of prescriptions = 4250000000

So y = 4250

Hence,

4250 = 86.83x + 2941.19

x = 15.07

Therefore,

Number of prescriptions will be 4250000000 in the year 2015 [If 2015 will not be correct then try 2016]
