Esme buys jackets for $500 each and prices them for $700 each. If the selling price is reduced by 20%, what's the profit percent
creativ13 [48]

12%

The cost Esme increased was 200, but then she reduced 20%of 700, which gives 140 dollars reduced. So, we subtract 140 from 200, which is 60 to find the actual increase.

Now, we follow the simple rules of percentage change

Increase divided by original times 100.

So, 60 divided by 500( not 700) times 100 = 12

22. (a) Is 3100 even or odd?<br> Even<br> Odd<br> Explain your answer.
mina [271]

Answer:

Even

Step-by-step explanation:

An even number is a number that can be divisible by 2 without a remainder. An odd number can be divisible by 2 and it's remainder is 1.

Let's put that to the test!

3100/2=1550 R:0

R is the remainder, which is 0. So the quotient thereby proves that 3100 is even and not odd.

Hope this helps!

The correct equation is P(t) = Po*e^(kt). Please enclose "kt" inside parentheses and use the " ^ " symbol to indicate exponentiation.


"k" is the growth constant, which here is 0.017. "t" is the number of yeasrs. P(7) is the population after 7 years. Po is the initial population, which in this case is 91 million.


The initial value, when t = 0, is 91 million.


After 7 years, the population, P(7), was P(7) = (91 million)*e^(0.017*7). This evaluates to P(7) = (91 million)*(1.070) = 96 million
