Number of Bacteria in 25g
To find the number of bacteria in 25g, we just need to multiply the number of bacteria in 1g by 25. This implies that the bacteria increase in a multitude of 25.
[tex]1g = 4.9*10^6\\25g = x[/tex]
Let's cross multiply both sides and solve for x
[tex]1g =4.9*10^6\\25g = x\\x = 25 * 4.9*10^6\\x = 122,500,000\\\\x = 1.225*10^8[/tex]
