To determine how much of the fee the client has paid, you need to calculate 70% of the total fee of $20,000. This is achieved by multiplying the total fee by the percentage completed.

Calculating this involves the following steps:

1. Convert the percentage into decimal form: 70% equals 0.70.

2. Multiply the total fee by this decimal:

\[

0.70 \times \$20,000 = \$14,000

\]

This means that at 70% completion, the client has paid $14,000. Understanding the process of calculating a percentage of a total fee is essential in managing clients' invoices accurately in the context of interior design projects, ensuring clarity in financial transactions and progress payments.
