Solve the problem.Light bulbs are often wired so that electricity can flow through either bulb, as illustrated in the accompanying figure. 
In this way, if one bulb burns out, the other bulb still works. If two light bulbs have resistances T and S,their combined resistance R is R = 
Evaluate the formula when T = 150 and S = 250. Round to the nearest hundredth.
A. R = 46.88
B. R = 0.01
C. R = 93.75
D. R = 140.63
