Total number of points possible = 700 (6 tests plus one yet to be taken)
\n" ); document.write( "Total number scored thus far = 79 * 6, or 474
\n" ); document.write( "Number of points necessary for an average of 80 = 80*700, or 560
\n" ); document.write( "Subtract the number of points earned from the number desired.
\n" ); document.write( "560-474 = 86 on the next test to have an 80 average
