Problem Analysis

Tanya found 15 more nuts than Marina and then gave Marina 8 nuts. We need to determine who has more nuts now and by how many.

Solution

Let's start by calculating the number of nuts Tanya had before giving 8 nuts to Marina. We can do this by subtracting 8 from the total number of nuts Tanya found.

Tanya found 15 more nuts than Marina, so if we let the number of nuts Marina found be x, then Tanya found x + 15 nuts.

After giving 8 nuts to Marina, Tanya has (x + 15) - 8 nuts.

To find out who has more nuts, we need to compare the number of nuts Tanya has now with the number of nuts Marina has.

Let's solve this problem step by step.

1. Let the number of nuts Marina found be x. 2. Tanya found 15 more nuts than Marina, so Tanya found x + 15 nuts. 3. Tanya gave 8 nuts to Marina, so Tanya has (x + 15) - 8 nuts now. 4. Marina has x nuts. 5. To determine who has more nuts, we need to compare the number of nuts Tanya has with the number of nuts Marina has. 6. If Tanya has more nuts, we subtract the number of nuts Marina has from the number of nuts Tanya has to find the difference. 7. If Marina has more nuts, we subtract the number of nuts Tanya has from the number of nuts Marina has to find the difference.

Let's calculate the number of nuts each girl has now.

Calculation

Let's calculate the number of nuts each girl has now using the given information.

Let x be the number of nuts Marina found.

Tanya found x + 15 nuts.

After giving 8 nuts to Marina, Tanya has (x + 15) - 8 nuts.

Marina has x nuts.

To determine who has more nuts, we compare the number of nuts Tanya has with the number of nuts Marina has.

If Tanya has more nuts, we subtract the number of nuts Marina has from the number of nuts Tanya has to find the difference.

If Marina has more nuts, we subtract the number of nuts Tanya has from the number of nuts Marina has to find the difference.

Let's calculate the number of nuts each girl has now.

Tanya has (x + 15) - 8 nuts.

Marina has x nuts.

To determine who has more nuts, we compare the number of nuts Tanya has with the number of nuts Marina has.

If Tanya has more nuts, we subtract the number of nuts Marina has from the number of nuts Tanya has to find the difference.

If Marina has more nuts, we subtract the number of nuts Tanya has from the number of nuts Marina has to find the difference.

Answer

The number of nuts each girl has now depends on the number of nuts Marina found. If Marina found x nuts, then:

- Tanya has (x + 15) - 8 nuts. - Marina has x nuts.

To determine who has more nuts, we compare the number of nuts Tanya has with the number of nuts Marina has.

If Tanya has more nuts, we subtract the number of nuts Marina has from the number of nuts Tanya has to find the difference.

If Marina has more nuts, we subtract the number of nuts Tanya has from the number of nuts Marina has to find the difference.

Please provide the value of x (the number of nuts Marina found) to calculate the final answer.
