Algebra.Com's Answer #505433 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! The admission fee at a fair is $2 for children and $4 for adults. \n" ); document.write( "On a certain day, 2,000 people enter the fair and $6,000 is collected. \n" ); document.write( " How many children and how many adults went to see the fair on that day? \n" ); document.write( ": \n" ); document.write( "Let a = no. of adults \n" ); document.write( "Let c = no. of children \n" ); document.write( ": \n" ); document.write( "From the given information, we can derive two simple equations \n" ); document.write( "the total no. of people \n" ); document.write( "a + c = 2000 \n" ); document.write( "and \n" ); document.write( "the total amt of $ received \n" ); document.write( "4a + 2c = 6000 \n" ); document.write( ": \n" ); document.write( "You can use substitution or elimination, we will use elimination \n" ); document.write( "multiply the 1st equation by 2 and subtract from the 2nd equation \n" ); document.write( "4a + 2c = 6000 \n" ); document.write( "2a + 2c = 4000 \n" ); document.write( "-----------------subtraction eliminates c, find a \n" ); document.write( "2a = 2000 \n" ); document.write( "a = 2000/2 \n" ); document.write( "a = 1000 adults \n" ); document.write( ": \n" ); document.write( "It's a simple thing to find the no. of children, I'll let you do that \n" ); document.write( "Check your solutions in the 2nd equation \n" ); document.write( " |
