\n" ); document.write( "The entry tickets at a community fair cost $5 for children and $10 for adults. On a certain day 1000 people entered in the fair and $7,100 is collected. How many adults and how many children were at the fair?
\n" ); document.write( "
Let number of adults be A, and number of children, C
\n" ); document.write( "Then we get: A + C = 1,000 ------ eq (i)
\n" ); document.write( "Also, 10A + 5C = 7,100_____5(2A + C) = 5(1,420)_____2A + C = 1,420 ----- eq (ii)
\n" ); document.write( " ---- Subtracting eq (i) from eq (ii)
\n" ); document.write( "Subtract value of \"A\" from 1,000 to get the number of children. \n" ); document.write( "
\n" );
