IMO C

The ques says each flower pot is of different size and the total cost is 8.25$
Total # of pots = 6
Let the cost of the smallest pot = x
The cost of each successive pot will be (cost of prev pot + 0.25)

x+(x+0.25)+(x+0.5)+(x+0.75)+(x+1)+(x+1.25)=8.25

6x+3.75=8.25
6x=4.5
x=0.75

The cost of the smallest pot = 0.75
Cost of the largest pot = 0.75+1.25 = 2

Whats the OA??
