\n" ); document.write( " Nadia's average earnings are $780 per week. What is the average value of her weekly sales?
\n" ); document.write( "------
\n" ); document.write( "E(x) = 400 + 0.05x
\n" ); document.write( "------
\n" ); document.write( "Solve::
\n" ); document.write( "400 + 0.05x = 780
\n" ); document.write( "0.05x = 380
\n" ); document.write( "x = 38000/5
\n" ); document.write( "x = 7600 dollars (amt. of sales)
