Luke should rent 4 droids.

Step-by-step explanation:

Complete question is attached in Fig 1

According to this

x     0       1         2         3         4        5

y     0       25      45       60      70       75

Plotting these points on graph as shown in Fig 2

No. of droids plotted on X-axis

Required no. of barrels on y-axis

According to graph if a droid costs 65 republic credits per month then Luke should rent 3.5 droids. To rent half a droid is not possible so rounding off to upper nearest which is 4. so Luke should rent 4 droids.
