Answer:
The correct options are:
c > 0
c + t ≥ 60
6c + 4c ≤ 300
Explanations:
Total area of garden = 300 square feet
Space required to plant 1 cucumber = 6 square feet
Space required to plant 1 tomato = 4 square feet
The number of cucumber = c
The number of tomato = t
Total number of plants is at least 60.
That is, total number of plants ≥ 60
Total number of plants = Number of cucumber + number of tomatoes
Total number of plants = c + t
Since total number of plants ≥ 60
c + t ≥ 60
Total area required to grow all the cucumber plants = 6c
Total area required to grow all the tomato plants = 4c
Since the total area of land is 300 square feet, the students cannot grow plants that will take more than the available land.
Therefore, 6c + 4c ≤ 300
Since the students want to plant some of each type of plants, it means
c > 0, and t > 0
