To determine which shade of gray paint can be made with 16 gallons of black paint and 2 gallons of white paint, we need to first calculate the ratio of black paint to white paint in the mixture.
We have:
- Black paint: 16 gallons
- White paint: 2 gallons
Now, let's find the ratio: \[ \text{Ratio of Black:White} = \frac{\text{Black}}{\text{White}} = \frac{16}{2} = 8:1 \]
Now, we can compare this ratio to the ratios provided for the different shades of gray:
- Gray Pearl: 1:20
- Urban Gray: 1:16
- Gray Fox: 2:1
- Volcanic Gray: 8:1
The ratio of the mixture (8:1) matches the ratio for Volcanic Gray.
Thus, the correct answer is: D. Volcanic Gray
