If 6 staplers weigh 13 ounces how much do 7 staplers weigh? Give answer as mixed number.

15

Step-by-step explanation:

Set up a proportional relationship equation and solve how much 7 staplers weighs.

   solve by cross product

6x = 91

x = 91/6  

Now  convert 91/6  to a mixed number.

6 will go into 91  , 15 times remainder  1  so as a mixed fraction will be  15

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
