the outdoors club held a car wash to raise money they washed cars for 5$ each and vans for 7$ each. they washed 45 vehicles and earned 243$. how many o each vehicle did they wash?
\n" ); document.write( "------------------
\n" ); document.write( "Equation:
\n" ); document.write( "Quantity:: c + v = 45 vehicles
\n" ); document.write( "Value:::: 5c + 7v = 2435 dollars
\n" ); document.write( "------------------------
\n" ); document.write( "Modify for elimination::
\n" ); document.write( "5c + 5v = 5*45
\n" ); document.write( "5c + 7v = 243
\n" ); document.write( "--------
\n" ); document.write( "Subtract and solve for \"v\":
\n" ); document.write( "2v = 18
\n" ); document.write( "v = 9 (# of vans washed)
\n" ); document.write( "----
\n" ); document.write( "Solve for \"c\"::
\n" ); document.write( "c + 9 = 45
\n" ); document.write( "c = 36 (# of cars washed)
\n" ); document.write( "==================
