i believe the implicit assumption in this problem is that the same amount of toys needs to be produced regardless of the number of elves working on them.
\n" ); document.write( "if there are 18 elves working and they each produce 20 toys each then the total production is 18 * 20 = 360 toys.
\n" ); document.write( "if 9 of them are sick then there are only 9 left to make 360 toys so each elf has to make 40 toys.
\n" ); document.write( "the inverse variation formula is y = k/x
\n" ); document.write( "y is the number of elves and x is the number of toys each produces.
\n" ); document.write( "we first solve for k using known facts.
\n" ); document.write( "when y = 18, x = 20 and the formula becomes:
\n" ); document.write( "18 = k / 20
\n" ); document.write( "solve for k to get k = 360.
\n" ); document.write( "when y is equal to 9, this formula now becomes:
\n" ); document.write( "9 = k / x
\n" ); document.write( "k is always equal to 360 so this formula now becomes:
\n" ); document.write( "9 = 360 / x
\n" ); document.write( "solve for x to get:
\n" ); document.write( "x = 360 / 9 = 40
\n" ); document.write( "with less elves working, each elf needs to produce more toys.
\n" ); document.write( " \n" ); document.write( "
\n" );
