A watch cost 75.99. If the sales tax rate is 6.25 percent, what is the amount of sales tax. Plus, please show your work.
rusak2 [61]
So the watch costs 75.99 including sales tax.

The sales tax is 6.25% of the value of the watch.

100% of the value of the watch is n.

100% + 6.25% of the value of the watch is 106.25/100 * n = 75.99

Let's calculate the sales tax...

\frac { 106.25 }{ 100 } \cdot n=75.99\\ \\ 106.25\cdot n=7,599\\ \\ n=\frac { 7,599 }{ 106.25 }

\\ \\ =71.52\\ \\ Sales\quad Tax\quad is\quad Therefore:\\ \\ 75.99\quad -\quad 71.52\quad =\quad 4.47

Bacteria in a culture increase at a rate proportional to the number of bacteria present. An initial population of 300 triples in
beks73 [17]

Answer:

<em>After 24 hours, there will be 4191 bacteria present in the culture.</em>

<em></em>

Step-by-step explanation:

Initial number of bacteria = 300

amount in 10 hrs = 3 x 300 = 900

time taken = 10 hours

Bacterial growth is exponential, ans so we use the equation

N = N'e^{kt}

where N is the final amount

N' is the initial amount

k is the growth constant

t is the time

For this first case, we have

900 = 300 x e^{k*10}

3 = e^{10k}

take natural log of both sides, we'll have

ln 3 = ln e^{10k}

1.0986 = 10k

k = 1.0986/10 = 0.10986

using the growth constant above, we calculate for a day which is 24 hours

N = N'e^{kt}

N = 300 x e^{0.10986*24}

N = 300 x e^{2.637}

N = 300 x 13.97

N = <em>4191 bacteria</em>
