Answer:
$4,000
Step-by-step explanation:
For computation of the government's total support payments to producers first we need to find out the surplus units which is shown below:
Floor price = $40
![Q_s = 280](https://img.qammunity.org/2021/formulas/business/college/2gz8egdrap3rolsb4zz4io81l4b00ue4v8.png)

![Q_s - Q_d](https://img.qammunity.org/2021/formulas/business/college/6kso1j91rah3uu4xtw75pcrl673m2d9y8j.png)
= 280 - 180
= 100
Therefore,
The Total support payments to producer = Price floor × Surplus units
= $40 × 100
= $4,000
So, for determining the total support payment to producer we simply multiply the price floor with surplus units.
