Final answer:
Julio has 12 dollars and Dan has 7 dollars.
Step-by-step explanation:
To represent the problem situation, let's assign variables to the amounts of money that Julio and Dan have. Let J represent the amount of money Julio has and let D represent the amount of money Dan has.
We are given that altogether they have 19 dollars, so we can write the equation J + D = 19. We are also given that Julio has 5 more dollars than Dan, so we can write the equation J = D + 5. Now we have a system of equations to solve.
Substituting the second equation into the first equation, we get (D + 5) + D = 19. Combining like terms, we have 2D + 5 = 19. Subtracting 5 from both sides, we have 2D = 14. Dividing both sides by 2, we have D = 7. Plugging this value back into the second equation, we can find that J = 12.
Therefore, Julio has 12 dollars and Dan has 7 dollars.
