There are 25 plants in arts garden. There are four times as many tomato plants as bean plants. How many tomato and bean plants are there?

Let b represent bean plants.

b + 4b = 25

Solve for b.

To solve this problem, we can set up a system of equations.

Let's say the number of bean plants is "B", and the number of tomato plants is "T".

From the problem, we are given two pieces of information:

1) There are 25 plants in total, so:

B + T = 25

2) There are four times as many tomato plants as bean plants, so:

T = 4B

Now, we can substitute the value of "T" from the second equation into the first equation:

B + 4B = 25

Combining like terms:

5B = 25

Divide both sides by 5:

B = 5

Now we know there are 5 bean plants. To find the number of tomato plants, we can substitute the value of "B" into the second equation:

T = 4 * 5

T = 20

Therefore, there are 5 bean plants and 20 tomato plants.
