Sofia is helping set up for a wedding. There are 80 chairs that need to be arranged in a room, and 60% of those chairs are still stacked in the corner. How many chairs are stacked?

48

Step-by-step explanation:

10% of 80 is 8 and 20% is 16 so lets do 40% which is 32 60%  32+16=48  8+10=80

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
