Answer: The total income during those years is $11325.
Step-by-step explanation:
Since we have given that
Income from snowplowing is given by
[tex]f(x)=35.5x+6,\\\\\text{where x is the snowfall in inches received during a winter}[/tex]
if Amount of snow received in 2006 = 53
Income is given by
[tex]f(x)=35.5x+6\\\\f(53)=35.5\times 53+6\\\\f(53)=1887.5[/tex]
Amount of snowfall received in 2007 = 42
Income is given by
[tex]f(x)=35.5x+6\\\\f(42)=35.5\times 42+6\\\\f(42)=\$1497[/tex]
Amount of snowfall received in 2008 = 55
Income is given by
[tex]f(x)=35.5x+6\\\\f(55)=35.5\times 55+6\\\\f(55)=\$1958.5[/tex]
Amount of snowfall received in 2009 = 63
Income is given by
[tex]f(x)=35.5x+6\\\\f(63)=35.5\times 63+6\\\\f(63)=\$2242.5[/tex]
Amount of snowfall received in 2010 = 58
Income is given by
[tex]f(x)=35.5x+6\\\\f(58)=35.5\times 58+6\\\\f(58)=\42065[/tex]
Amount of snowfall received in 2011 = 47
Income is given by
[tex]f(x)=35.5x+6\\\\f(47)=35.5\times 47+6\\\\f(47)=\$1674.5[/tex]
So, Total income during those years is given by
[tex]1887.5+1497+1958.5+2242.5+2065+1674.5\\\\=\$11325[/tex]
Hence, the total income during those years is $11325.
