The total number of people, P, who have been infected with a contagious virus t weeks after the epidemic began is given by the following formula. 1620 1+4(0.5) Complete parts a through d below a. How many people originally had the virus? Originally people were infected.

Originally 324 people were infected.

Step-by-step explanation:

Given the function

P = 1620/(1 + 4(0.5)^t)

Where;

P is the total number of people, who have been infected with a contagious virus t weeks after the epidemic began.

t is the number of weeks after the epidemic began.

To determine the number of people who originally have the virus. At this time

t = 0

Therefore, substituting t = 0 into the function of P

P = 1620/(1 + 4(0.5)^0)

P = 1620/(1 + 4)

P = 324 people.

Originally 324 people were infected.
