The cost for burning a 75 watt bulb is given by the function c(h) = 0.0055h, where h represents the number of hours that the bulb burns.

\n" ); document.write( "(a) How much does it cost to burn a 75 watt bulb for 3 hours per night for a 28 day month? Express your answer to the nearest cent.
\n" ); document.write( "c(3*28) = 0.0055(3*28) = $0.462
\n" ); document.write( "----------------------------------
\n" ); document.write( "(b) Graph the function c(h) = 0.0055h. (Do this on paper. Your instructor may ask you to turn in this graph.)
\n" ); document.write( "\"graph%28400%2C300%2C-5%2C500%2C-5%2C4%2C0.0055x%29\"

\n" ); document.write( "(d) Use c(h) = 0.0055h to find the exact cost, to the nearest cent, of burning a 75 watt bulb for 295 hours.
\n" ); document.write( "c(295) = 0.0055(295) = $1.62
