Question

Write and solve an equation for the number of flats Yoshi should buy.

Step-by-Step Solution

Answer

The number of flats is 2.5.

Step 1. Given information.

A flat of plants contains 12 plants.

Number of rows = 3

Plant per row = 10

Step 2. Write the equation.

Consider the number of flats be n. The total number of rows is 3.

So, the total number of plants is given by

$3\times 10=30$

Then, the equation to find the number of flats is:

$12n=30$

Step 3. Solve the equation.

The equation $12n=30$ can be written as in below.

$$\begin{gathered} 12n=30 \\ n=\frac{30}{12} \\ n=2.5 \end{gathered}$$

Therefore, Yoshi should buy 2.5 flats.
