Answer:
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.
