Answer:

2560 units of bacteria will be present after 15 hours

Step-by-step explanation:

initial number: 80 units of bacteria

2X every 3 hours

80(2) = 160 1st 3 hours = 3

160(2) = 320 2nd 3 hours = 6

320(2) = 640 3rd 3 hours = 9

640(2) = 1280 4th 3 hours = 12

1280(2) = 2560 5th 3 hours = 15
