document.write( "A movie theater charges $7 for adults, $5 for children under age 17, and $4 for seniors over age 60. For one showing of the movie Batman the theater sold 222 tickets and took in $1383. If twice as many adult ticket swere sold as the total for children and senior tickets, how many tickets of each kind were sold?\r

Algebra.Com's Answer #253663 by jrfrunner(365) You can put this solution on YOUR website! you have 3 unknowns, so you need to set up 3 seperate equations; \n" ); document.write( "-- \n" ); document.write( "let A=number of Adult tickets sold \n" ); document.write( "let C=numer of children tickets sold \n" ); document.write( "let S=numbe of senior tickets sold \n" ); document.write( "-- \n" ); document.write( "equation 1 (number of tickets): A+C+S=222 \n" ); document.write( "equation 2 (revenues): 7A+5C+4S=1383 \n" ); document.write( "equation 3 (relationship): 2A=S+C \n" ); document.write( "-- \n" ); document.write( "so now you have 3 equations in 3 unknowns \n" ); document.write( " |
