Raina, Justin, and cho have $79 in their wallets. Raina has $5 leas than Justin. Cho has 2 times what Justin has. How much does each have

Respuesta :

Answer: Justin: 21 dollars, Raina: 16 dollars, Cho: 42 dollars.

Step-by-step explanation:

Let's say that Justin has x dollars.

Since Raina has 5 dollars less than Justin, Raina has (x - 5) dollars.

Since Cho has 2 times of what Justin has, Cho has 2x dollars.

In total, they have 79 dollars. So by adding up our quantities, they will equal 79 dollars.

x + (x - 5) + 2x = 79

So: 4x - 5 = 79

So 4x = 84

So x = 21

Therefore Justin has 21 dollars

Since Raina has 5 dollars less than Justin, Raina has 16 dollars

Since Cho has 2 times of Justin, Cho has 42 dollars
