The interior length of a planter is 12 inches, and the planter contains a single row of p plants along that length. Each plant is one-half inch wide, and the space between adjacent plants, as well as between the plant on either end of the row and the planter, is always at least 1 inch but no more than 2 inches.
Select the Minimum and Maximum values of p that are jointly consistent with the given information. Make only two selections, one in each column.

one half = 0.5
Given you have p plants, total length of pots = 0.5p
If you draw out the pots of plants and planter, you'll notice the gaps are (p+1).
If there are 3 pots, there will be 4 gaps between the pots themselves and with the planter.
At least 1 inch distance = you'll be finding the max no of pots.
0.5p + (p+1)(1) <= 12
p<= 7.33
max = 7
At most 2 inch distance = you'll be finding the min no of pots
0.5p + (p+1)(2) >= 12
p>=4
min = 4

I considered one half as 3/2=1.5.
Let me know if this is correct?
