Algebra.Com's Answer #797945 by mahikab(11)![]() ![]() ![]() You can put this solution on YOUR website! Assume number of adults = a and number of children = c \n" ); document.write( "Therefore, \n" ); document.write( " a + c = 120 -------- (1) \n" ); document.write( "and 500a + 400c <= 80000 -----(2) \n" ); document.write( " \n" ); document.write( "When c=0, a <= 80000/500 = 160 \n" ); document.write( "When a=0, c <= 80000/400 = 200 \n" ); document.write( " \n" ); document.write( "So, the possible number of adults and children are: \n" ); document.write( "All values of (a, c) satisfying inequation (2) where a <= 160, c <= 200 \n" ); document.write( " \n" ); document.write( " |
