Richard's company bought 84.083 pounds of wood and 59.21 pounds of brick. How many pounds of material did the company buy in all?

To find the total amount of material bought, we add the weight of the wood (84.083 pounds) to the weight of the brick (59.21 pounds).

Total = 84.083 pounds + 59.21 pounds = <<84.083+59.21=143.293>>143.293 pounds
Therefore, Richard's company bought a total of 143.293 pounds of material.

To find the total weight of the materials Richard's company bought, we add the weight of wood and the weight of brick.

Wood weight = 84.083 pounds
Brick weight = 59.21 pounds

Total weight = Wood weight + Brick weight
Total weight = 84.083 pounds + 59.21 pounds

Evaluating the expression, we get:

Total weight = 143.293 pounds

Therefore, Richard's company bought a total of 143.293 pounds of material.

To find the total pounds of material that Richard's company bought, you can add the weight of wood and the weight of brick.

Wood: 84.083 pounds
Brick: 59.21 pounds

To add these two numbers, align the numbers vertically by their decimal points and then add each column.

```
84.083
+ 59.210
_________
```

Start by adding up the numbers in the rightmost column, which is the column without any decimal places. Here, it's the ones column.

3 + 0 = 3

Next, move to the next column to the left, which is the tenths column.

8 + 1 = 9

Now move to the next column, which is the hundredths column.

4 + 2 = 6

Finally, move to the last column, which is the thousandths column.

0 + 0 = 0

Now we have the sum of the weights:

84.083 + 59.210 = 143.293

Therefore, Richard's company bought a total of 143.293 pounds of materials.
