Respuesta :

Answer:

Josh had $18 and Carly had $8.

Step-by-step explanation:

Given:

Josh had $10 more than Carly.

Josh gave Carly half of his money, then Carly had more money than josh, so she gave Josh $4. Then they both had $13.

Question asked:

How much money did each person start?

Solution:

Let Carly start with money be [tex]x[/tex]

Then, Josh start with = [tex]x+10[/tex]

According to question:

For Josh :  [tex]x+10[/tex]

Josh gave Carly half of $10 and received $4 from Carly having $13 at last, so the equation will be:-

[tex]x+10-\frac{1}{2} (x+10)+4=13\\\\ x+10-\frac{x}{2}-5 +4=13\\ \\ x-\frac{x}{2}+9=13\\\\ \frac{2x-x}{2} +9=13\\\\ \frac{x}{2} +9=13[/tex]

Subtracting both sides by 9,

[tex]\frac{x}{2} =4\\[/tex]

Multiplying both sides by 2,

[tex]x=8[/tex]

Carly start with money be [tex]x[/tex] = $8

Josh start with = [tex]x+10[/tex] = 8 + 10 = $18

Therefore, at starting, Josh had $18 and Carly had $8.
