Final answer:
To calculate the advanced payment rate specified in the FFP contract, multiply the contract value without profit by 80%, is $704,000..
Step-by-step explanation:
To calculate the advanced payment rate specified in the FFP contract, we first need to determine the total contract value after subtracting the profit. The total contract value is $1,000,000 and the profit is $120,000, so the contract value without profit is $880,000. To find the advanced payment rate, we multiply the contract value without profit by 80%:
Advanced Payment Rate = $880,000 * 0.8 = $704,000
Therefore, the advanced payment rate specified in the FFP contract is $704,000.
