Question 181584
The band members sold tickets to their concert performance.  There were 16 more than twice as many $6 tickets as $5 tickets.  The total sales were $1643.  How many tickets of each price were sold?
:
let x and y be the number of $5 and $6 tickets sold respectively
:
y=2x+16..........eq 1
5x+6y=1643.......eq 2
:
take y's value of 2x+16 from eq 1 and plug it into eq 2
:
5x+6(2x+16)=1643
:
5x+12x+96=1643
:
17x=1547
:
{{{highlight(x=91)}}}$5 tickets sold
:
{{{highlight(y=2(91)+16=198)}}}$6 tickets sold
