Answer:
62
Step-by-step explanation:
50
+
12
_____
62
Tree = (-4,2)
Pool = (3,4)
Ant Hill = (1,-4)
Barbecue Grill = (-5,-2)
Flowers = (0,3)
% times amount of each part = % times amount of mix
x = amount of 10%
100 = amount of 100%
x + 100 = amount of 40% mix
10x + 100(100) = 40(x + 100)
10x + 10,000 = 40x + 4,000
-10x - 4000.....-10x - 4000
------------------------------------- 6000 = 30x
so x = 6000 ÷ 30 = 200 mL
