Answer:

Steve has a total of $140.

Step-by-step explanation:

At first, we know that Steve has $140.50. Next, he loaned $50 to a friend. This tells us that this money went out of his account.

140.50 - 50 = $90.50

So now, Steve has only $90.50 left.

Then, he spent $31.25. This also tells us that his went out of his account, so we must subtract it.

90.50 - 31.25 = $59.25

Now, Steve has $59.25 left.

Finally, Steve received an $80.75 paycheck from work. This tells us that this money went in to his account.

59.25 + 80.75 = $140

Therefore, Steve now has a total of $140.

Suppose that poaching reduces the population of an endangered animal by 6​% per year. Further suppose that when the population o
artcher [175]

If poaching reduces the population of an endangered animal by 6% and the criteria of population extinction is 20 with present population 1500 then it will take 3.62 years to reach to the mark of extinction.

Given Poaching reduces the population of endangered animals by 6% per year. The criteria of population extinction is 20. Present population being 1500.

Number of years taken by the population of endangered animals to reach to 20 mark can be calculated as under:

20=1500*(1-0.06)^{n}

20=1500*0.94^{n}

20/1500=0.94^{n}

0.133=0.94^{n}

take log both sides

log(0.133)=log0.94^{n}-------1

log(0.133)=nlog (0.94)

put the values log values:

log(0.133)=-0.8761

log(0.94)=-0.0268

Taking 1

-0.8761=n*(-0.0268)

n=0.8761/0.0268

n=3.269

Hence to reach level of 20 the population takes 3.2 years.

Answer:

$2,410.69

Step-by-step explanation:

$1,950 x 1.15 = $2,242.50 after 15% markup

$2,242.50 x 1.075 = $2,410.68 after the 7.5% sales tax.


or you can do:


$1,950 x 0.15 = $292.5 markup

$1,950 + $292.5 = $2,242.50

$2,242.50 x 0.075 = $168.19 for sales tax

$2,242.50 + $168.19 = $2,410.69 total
