The number of bacteria in a colony is growing exponentially. A scientist notes that the number of bacteria in the colony is 50. Two hours later, she
notes that the number of bacteria has increased to 80. If this rate of growth continues, how much more time will it take for the number of bacteria
to reach 100?
Aabout 0.95 hours
B. about 0.16 hours
C. about 9.80 hours
D. about 6.85 hours

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
