C = 1.6b
c + b = 442
1.6b + b = 442
2.6b = 442
b = 442 / 2.6
b = 170 <== Boston
c = 1.6b
c = 1.6(170)
c = 272 <== Colorado Springs
Y/22 would be the answer to your question.

Step-by-step explanation:
Add 4 to both sides and then multiply both sides by 3.
Area of a sphere = 4(pi)(r)^2
Reverse the equation to find the radius (r)
The answer will be in pi form
32/81(pi)
8/20.25(pi)
Square root of 8/20.25(pi) = radius
r = 2.8(rounded)/4.5(pi)
