Strain B started with a genetic mutation in patient zero that caused them to turn into a zombie. This strain differs from A in that all zombies can infect new people. Zombies infected with strain B can infect 1 person every minute.

1 answer

To calculate the number of zombies for Strain B over time, we start with 1 zombie (patient zero) and assume each zombie can infect 1 new person every minute. This leads to an exponential increase in the number of zombies.

Here's how the calculation works:

  • At minute 0: 1 zombie (patient zero)
  • At minute 1: 1 original zombie + 1 newly infected = 2 zombies
  • At minute 2: 2 original zombies (1 infects 1 new) + 2 newly infected = 4 zombies
  • At minute 3: 4 zombies (2 infecting 2 new) = 8 zombies
  • At minute 4: 8 zombies (4 infecting 4 new) = 16 zombies
  • At minute 5: 16 zombies (8 infecting 8 new) = 32 zombies
  • At minute 6: 32 zombies (16 infecting 16 new) = 64 zombies
  • At minute 7: 64 zombies (32 infecting 32 new) = 128 zombies
  • At minute 8: 128 zombies (64 infecting 64 new) = 256 zombies
  • At minute 9: 256 zombies (128 infecting 128 new) = 512 zombies

This is consistent with the doubling pattern, where the total number of zombies at each minute is twice that of the previous minute.

Now, let's complete the table:

| Minutes | Number of Zombies | |---------|-------------------| | 0 | 1 | | 1 | 2 | | 2 | 4 | | 3 | 8 | | 4 | 16 | | 5 | 32 | | 6 | 64 | | 7 | 128 | | 8 | 256 | | 9 | 512 |

Make sure to fill in the "Math Input" rows with the number of zombies according to the corresponding minutes above.
