Adrian purchased 20 ballet tickets for a total of $1110.How much would it have cost him for 150 ballet tickets solve using both the rate and proportion methods
\n" ); document.write( ":
\n" ); document.write( "The rate method finds the cost of 1 ticket times number of tickets required:
\n" ); document.write( " $\"1110%2F20\"$ * 150 = $8,325
\n" ); document.write( ":
\n" ); document.write( "The proportions method, c = cost
\n" ); document.write( " $\"20%2F150\"$ = $\"1110%2Fc\"$
\n" ); document.write( ":
\n" ); document.write( "Cross multiply
\n" ); document.write( "20c = 150*1110
\n" ); document.write( "20c = 166500
\n" ); document.write( "c = 166500/20
\n" ); document.write( "c = $8325 \n" ); document.write( "
