If the sample of bacteria is growing at an hourly rate of 15% continuously and the bacteria began with 11 bacteria then there will be 244.178 samples bacteria after 21 hours.
Given growth of bacteria 15% ,bacteria at beginning 11.
We have to find the number of sample of bacteria after 21 hours.
We have to first form exponential function which shows the growth of bacteria in variable t.
Exponential function which shows the sum is y=P
where P is initial amount ,
r is rate and
y is the sum
So in our problem P=11 and r=0.15
y=11*
To find the samples after 21 hours we have to put t=21.
y=11
y=11*
y=11*22.198 (=22.198 from e table)
y=244.178
Hence the samples after 21 hours will be 244 approximately.

Answer:
Well the original price would be $44
Step-by-step explanation:
So make an equation
Lets make X stand for the price before the deduction
so x-x(0.3)=30.80
Subtracting the X by x(0.3) would tell us the price, the 0.3 stands for 30 percent and we know its 30 percent of X so we subtract that since 0.3x would give the change
Now just solve the equation
You’ll get 44.
So for every time you have a number before a “()” you have to cross multiply
Your answer is 323
There are 120 calories per cup. So, in four cups there should be 4×120 = 480 calories.
