Answer:

Step-by-step explanation:
represents the commission on
dollars of sales.
For the first $10,000 of sales, the commission is $1400.
For each additional $10,000, the commission is $700.
The total value is $65,000.
The first $10,000 implies a commission of $1400.
The rest is $55,000, which represents 5 times $10,000 and $5,000. The additional commission is 5 times $700, which is $3500.
Therefore, the total commission for the sale of $65,000 is $4,900.
