The virus had infected 2000 cells in Joel's body by the second day and 2240 cells after 3 more hours. Interferon proteins then slowed the viral replication rate by 80%, so after the next 8 hours the total infected cells would be fewer than if the replication had continued unchecked.

1. Question 3 Viruses

2. The amount of virus infected cells within Joel’s body reached 2000 by the second day. After 3 hours, the virus had infected a total of 2240 cells. At this moment, cells in Joel’s body produce proteins called interferon that act as antibodies to prevent viral replication and slow down the rate of growth by 80%. How many cells total will be infected after the next 8 hours?
