Answer:
6. c <= 1
7. p >= 1 000 000 000
Explanation:
6. a dollar or less = $1 dollar or less than $1; therefore, <= sign is used
7. at least = the minimum of the number given; therefore, >= sign is used.
(if you are struggling with which sign is the "greater than" or "less than," remember that the bigger ones are what they are most likely to eat, for example, 100 > 1; imagine signs like Pacman eating those balls)
