Question
is this the correct formula for me to solve this?
A bacteria culture has 2,000 bacteria. The number of bacteria increases by 5% each hour. How many bacteria are there after 12 hours?
2,000*0.05^(12-1)

It is like compound interest (1+r)^n
2,000 * (1.05)^12
12 not 11 because it is at the END of the hour
at end of hour we have 1.05 times the initial amount the original + .05 * original = original (1 + .05)
2,000 * (1.05)^12
12 not 11 because it is at the END of the hour
at end of hour we have 1.05 times the initial amount the original + .05 * original = original (1 + .05)
