c
Step-by-step explanation:
if it is on sale for 40 percent off, then it would be 60 percent of the original price. 18/6=3. 3*4=12. 3*6=18. 12 + 18 = 30
Bacteria length = 1mm
It will triple four times by 40 min.
This can be shown as 3 to the power of 4; 3⁴ = 81
Original length * growth factor = final length
1 mm * 81 = final length
81 = final length
After 40 mins, the bacteria colony will be 81 mm in length.
