1. Problem Description

The problem consists of two sub-problems.

First, Alan has 45 beans and plants 3 beans in each pot. We need to find out how many pots he needs.

Second, Leila puts 4 seeds in each of her pots. She uses 6 pots and has 1 seed left over. We need to find out how many seeds she started with.

2. Solution Steps

First Problem:

To find the number of pots Alan needs, we divide the total number of beans by the number of beans in each pot.

Number of pots = Total beans / Beans per pot

Number of pots = $45 / 3$

Number of pots = $15$

Second Problem:

To find the number of seeds Leila started with, we first calculate the number of seeds she used in the 6 pots. Then, we add the 1 seed she has left over.

Seeds in pots = Pots used * Seeds per pot

Seeds in pots = $6 * 4$

Seeds in pots = $24$

Total seeds = Seeds in pots + Leftover seeds

Total seeds = $24 + 1$

Total seeds = $25$

3. Final Answer

For the first problem: Alan needs 15 pots.

For the second problem: Leila started with 25 seeds.
