A residential water bill is based on a flat fee of $10 plus a charge of $0.75 for each 1000 gal of water used.
\n" ); document.write( ":
\n" ); document.write( "Let g = no. of thousands of gallons used
\n" ); document.write( "f(g) = .75g + 10
\n" ); document.write( ":
\n" ); document.write( " Find the number of gallons of water a family can use and have a monthly water bill that is less than $25.
\n" ); document.write( ":
\n" ); document.write( ".75g + 10 = 25
\n" ); document.write( "subtract from both sides
\n" ); document.write( ".75g = 15
\n" ); document.write( "g = 15/.75
\n" ); document.write( "g = 20 thousand gallons \n" ); document.write( "
