Which is a better buy? 9.30 for 10 sharpies or 6.55 for 7?

The 10 sharpies because you get more for less because if you by 7 you get less for more with that amount.

9.30 for 10

Step-by-step explanation:

9.30/10=.93

6.55/7=.94(I rounded this number the  original is .9357142857)

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.
