Final answer:
Debra has $21, Miguel has $16, and Pablo has $63.
Step-by-step explanation:
We can solve this problem using a system of equations. Let's let D represent the amount of money Debra has, M represent the amount of money Miguel has, and P represent the amount of money Pablo has.
From the problem, we know that Miguel has $5 less than Debra, so M = D - 5. We also know that Pablo has 3 times what Debra has, so P = 3D.
We are also given that the total amount of money is $100, so D + M + P = 100.
Let's solve this system of equations to find the values of D, M, and P.
Substituting the values of M and P from the other equations into the last equation, we get D + (D - 5) + 3D = 100. Simplifying this equation gives us 5D - 5 = 100. Adding 5 to both sides gives us 5D = 105. Dividing both sides by 5 gives us D = 21.
Substituting this value of D back into the other equations, we find that M = 16 and P = 63.
Therefore, Debra has $21, Miguel has $16, and Pablo has $63.
