52) 115-3=112 that were given away
Now divide 112 by each, seeing if they give you a non mixed number.
The only one that would give you a full number would be 28. So there are 28 kids in his class.
54) 19-4=15
Now double 15 since he sold half, so he started with 30 stamps originally.

Answer:
8/3
Step-by-step explanation:
i put equations as this:
x+40 = y
where x is galllons of pure mixture and y is the gallons of the new mixture
the other equation i id was:
x+0.2(40) = 0.25y
x+8 = 0.25y
y = 4x+32
solve using substitution
(x+40) = 4x+32
x = 4x-8
-3x = -8
x = 8/3
