The first option is asphalt, which costs $2,200.00 to install, but requires her to apply sealant every year at the rate of $115.00 per treatment. The other option is concrete, which costs $3550.00 and requires no annual maintenance.\r

Algebra.Com's Answer #533750 by JulietG(1812)![]() ![]() You can put this solution on YOUR website! First option: 2200 +115a = final cost, where a is the number of years. \n" ); document.write( "Second option: 3550 = final cost \n" ); document.write( "There is no variable in the second option, and therefore not a linear relationship. \n" ); document.write( "In the first option, if we plotted this on a graph, we would BEGIN at 2200 and then rise 115 each year. This creates a line. The line does not begin at zero, but it is still a linear equation, just starting at the fixed cost. \n" ); document.write( ". \n" ); document.write( "If Rhonda is going to stay in her house, she should lay the concrete ;-). \n" ); document.write( " |
