Bethany borrows $8000 from the bank. If she owes a total of $12,800 after 4 years of continuously compounding the interest, at what rate did she borrow?

$62

Step-by-step explanation:

The total weight of the semitruck and its load is 31 tons. Let's convert this to pounds:

1 ton = 2000 lb

31 tons = 2000 * 31 = 62000 lb

We know every 10 lb will be priced at $0.01, so divide 62000 by 10 to find how many times we need to pay $0.01:

62000 ÷ 10 = 6200

Each of these 6200 times, we need to pay $0.01 so multiply these together:

6200 * 0.01 = 62

The answer is $62.
