If something is growing at a rate of 7% a month, that means you take the original amount and multiply it by 0.07 and then add it to the original amount.
Luckily, there is a quick way of doing this. Just take the original amount and multiply it by 1.07. Since there are a total of 7 months, we must multiply the original amount by 1.07 seven times.
So our answer is:
524 * 1.07^7 =
841.429 bacteria

7% = 0.07
since it is growing add that to 1 = 1.07
now that is to the power of length of time 1.07^7
now multiply
524 x 1.07^7 = 841.429 ( round answer as needed)
