each person starts with $8.

<u>Step-by-step explanation:</u>

Here we have , Josh had $10 more than Carly, so he gave Carly half of his money. Then Carly had more money than josh, so she gave Josh $4. Then they both had $13. We need to find  How much money did each person start  . Let's find out:

Suppose Carly had $x ,  Josh had $10 more than Carly i.e. $(x+10), so he gave Carly half of his money i.e.

⇒ \frac{x+10}{2} ,Now , Josh have $\frac{x+10}{2}  & Carly have x + \frac{x+10}{2} .

Then Carly had more money than josh, so she gave Josh $4 . So ,

Josh now have $(4+\frac{x+10}{2})  and  Carly now have $(x+\frac{x+10}{2} -4) . Since both are equal :

⇒  (x+\frac{x+10}{2} -4) = (4+\frac{x+10}{2})

⇒  x-4 = 4

⇒  x=8

Therefore , each person starts with $8.

Three numbers between 80 and 100 are prime numbers. What numbers are they? Eight numbers between 31 and 41 are composite numbers
Flura [38]
83, 89, and 97 are three primes between 80 and 100.

The primes between 30 and 50 are 31, 37, 41, 43, and 47, all of which are odd.  All other numbers between 30 and 50 are composite.

To mentally find 2*50*25, you could either first multiply 25 by 2, to get 50*50, which can easily be calculated as 2500, or you could multiply the 50 by 2, for a result of 100*25, which is clearly also 2500.

Suppose you invest $150 a month for 5 years into an account earning 7% compounded monthly. After 5 years, you leave the money, w
lisabon 2012 [21]

Answer:

About 0.3 billion dollars

Step-by-step explanation:

5 years = 60 months.

The 150 of the first month will be 150*1.07^60 in 5 years.

The 150 of the second month will be 150*1.07^59 in 5 years.

The 150 of the third month will be 150*1.07^58 in 5 years.

And so forth.

So we sum that up:

( sum_(n=1)^(60) 150×1.07^n)

And multiply with

× 1.07^(5×23)

to account for the increase in value in the following 23 years.
