Each letter is 0.39 + 3(0.25). Add them together.
$0.52 / 2 (2 cups in a pint)
3. 2/5 * 60 = 24 min = 40% hour.
However, this just tells us how long the "finishing" part took, not the entire homework. To know that, we need to know when he started.

This may be right, but I am not 100%:
1. rico wants to mail two letters, each weighing 4 ounces. For each letter, the first ounce costs $0.39. Each additional ounce costs $0.25. How much does it cost rico to mail his two letters.
0.39 * 2 = $0.78
(0.25 * 4) x 2 = $2.00
$ 2.00 + 0.78 = $2.78
2.if lemonade costs $0.52 per pint, what is the cost per cup?
$0.52 / 2 = $0.26
3. tyrone finished his math homework in two fifths of an hour.
60 / 5 = 12
12 * 2 = 24 mins.
a.how many minutes did it take tyrone to finish his math homework.
12 * 2 = 24 mins.
b.what percent of an hour did it take tyrone to finish his math homework.
40%
c. to answer a and b, what information that was not given did you need to know?
