A $9,600 invoice is split into three payments of 40%, 35%, and the remainder. What is the third payment?

To find the third payment, you first need to calculate the amounts of the first two payments based on the percentages provided.

The first payment is 40% of the total invoice amount, which can be calculated as:

[ 0.40 \times 9,600 = 3,840. ]

The second payment is 35% of the total invoice amount, calculated as:

[ 0.35 \times 9,600 = 3,360. ]

Now, you can find the total of the first two payments:

[ 3,840 + 3,360 = 7,200. ]

To find the remainder, which is the third payment, subtract the total of the first two payments from the total invoice amount:

[ 9,600 - 7,200 = 2,400. ]

Thus, the third payment is $2,400, making it the correct choice. This approach effectively breaks down the payment structure and ensures that all parts add up to the total invoice amount, providing clarity on how the percentages relate to the final amounts.
