Final answer:
Martina has $12, Alonzo has $22, and Deshaun has $36 in their wallets, giving a total of $70.
Step-by-step explanation:
Let's assume that Martina has $x in her wallet.
According to the information given, Deshaun has 3 times what Alonzo has. So, Deshaun has 3x dollars.
Also, Alonzo has 10 more than Martina, which means Alonzo has (x + 10) dollars.
Now, we know that the total amount of money in their wallets is $70.
Therefore, we can write the equation: x + 3x + (x + 10) = 70.
Simplifying the equation, we get: 5x + 10 = 70.
Subtracting 10 from both sides, we have: 5x = 60.
Dividing both sides by 5, we find that x = 12.
So, Martina has $12, Alonzo has $22 (12 + 10), and Deshaun has $36 (3 * 12).
Therefore, they have a total of $12 + $22 + $36 = $70 in their wallets.
