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. How much money did each person start?

Respuesta :

each person starts with $8.

Step-by-step explanation:

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.

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

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

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

⇒  [tex](x+\frac{x+10}{2} -4) = (4+\frac{x+10}{2})[/tex]

⇒  [tex]x-4 = 4[/tex]

⇒  [tex]x=8[/tex]

Therefore , each person starts with $8.
