Frazier has $1,200 in savings. he works because he is saving money for college, and he earns $9 an hour. if frazier saves 25 percent of his net pay, after 20 percent is taken out for tax, identify the expression which represents frazier's savings. a) 1.8x + 1,200 b) 3.6x + 1,200 c) 7.2x + 1,200 d) 9x + 1,200

the correct answer is A..!! I think...:(

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
