A super-secret handshake is set up with every other person in a cabin. You and another person in the cabin have one handshake. Now there are 14 total people in the cabin. How many handshakes will there be in all?

7 handshakes in all.

Step-by-step explanation:

If you and another person have one shake  and there are 14 total people in the cabin that means that there will be 7 handshakes  in all.

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
