Remember that when multiplying fractions, we multiply everything on the top and everything on the bottom.
a * b * c
(-2 / 5) * (20 / 32) * (-4 / 10)
(-2 * 20 * -4) / (5 * 32 * 10)
160 / 1600
1 / 10
Correct answer: D. 1/10

First we need to find k ( rate of growth)
The formula is
A=p e^kt
A future bacteria 4800
P current bacteria 4000
E constant
K rate of growth?
T time 5 hours
Plug in the formula
4800=4000 e^5k
Solve for k
4800/4000=e^5k
Take the log for both sides
Log (4800/4000)=5k×log (e)
5k=log (4800/4000)÷log (e)
K=(log(4,800÷4,000)÷log(e))÷5
k=0.03646
Now use the formula again to find how bacteria will be present after 15 Hours
A=p e^kt
A ?
P 4000
K 0.03646
E constant
T 15 hours
Plug in the formula
A=4,000×e^(0.03646×15)
A=6,911.55 round your answer to get 6912 bacteria will be present after 15 Hours

To find decimal, divide 13/50= 0.26
To find percent divide decimal above by 100 (or move decimal place to the right two places).
0.26/100= 26%
