A pattern of dots grows exponentially. The table shows the number of dots at each step of the pattern. step number 0 1 2 3
number of dots 1 5 25 125
Write an equation to represent the relationship between the step number, n, and the number of dots, y.
At one step, there are 9,765,625 dots in the pattern. At what step number will that happen? Explain how you know.

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
