Carlos began with twice as much money as David
had. After Carlos gave $12 to David, Carlos still had
$10 more than David. How much money did they
have combined at the start?

Respuesta :

Answer:

$102

Step-by-step explanation:

Carlos had twice as much money as david

x= david's initial money

Carlos' money = 2x

After carlos gave $12 to david, Carlos still had $10 more than david

2x-12=x+22

x=34 which means david initially had 34$

(34 x 2) carlos + 34 david = $102

check by plugging 34 back into the equation.
