The percent discount is 30%.
If you multiply $32 by .30, you will get $9.60. That is the amount of the discount. If you subtract $9.60 from $32, you will get $22.40 which is what he paid before tax. Therefore the percent discount is 30%.

Suppose that a colony of bacteria starts with 1 bacterium and doubles in number every half hour. how many bacteria will the colo

OverLord2011 [107]

Let $a_n$ represent the number of bacteria after $\frac{n}{2}$ hours.

so

$a_0$ is the number of bacteria after 0/2 = 0 hours

$a_1$ is the number of bacteria after 1/2 hours

$a_2$ is the number of bacteria after 2/2 = 1 hours and so on

so if we list a few terms of this sequence, we have:

$a_0=1$

$a_1=1*2$

$a_2=1*2*2$

$a_3=1*2*2*2$

$a_4=1*2*2*2*2$

so clearly, $a_n$ , the number of bacteria after $\frac{n}{2}$ hours, is equal to $2^{n}$ .

$a_4_8$ is the number of bacteria after

$\frac{n}{2}=\frac{48}{2}= 24$ hours.

Thus, we calculate $a_4_8$ , which is $2^{48}$ .

Answer: the number of bacteria after 24 hours is $2^{48}$ .
