Answer:
Red = 30 drops
Blue = 20 drops
Step-by-step explanation:
The ratio red to blue is 3 : 2
Sum of ratios = 3 + 2 = 5
Required purple paint = 50 gallons
So,

Now, Red drops = 3×10 = 30
Blue drops = 2×10 = 20
3^2 + 4^2 = c^2
sqrt(9) + sqrt(16) = c^2
Sqrt(25) = c^2
C = 5
The exponent on the P will be 5
