Final answer:
Lindsey has $5 and Bella has $15.
Step-by-step explanation:
Let's denote Lindsey's amount of money as x. From the given information, we can gather the following:
- Bella has 3 times the money as Lindsey, so Bella has 3x.
- Grace has 5 more than Lindsey, so Grace has x + 5.
- Bella has the same amount of money as Lindsey and Grace combined, so 3x = x + x + 5.
Simplifying the equation, we have 3x = 2x + 5.
Subtracting 2x from both sides, we get x = 5.
Therefore, Lindsey has $5. To find Bella's amount of money, we can substitute x = 5 into the equation 3x. Bella has 3(5) = $15.
