Answer:
7
Step-by-step explanation:
2n - 6 = 8. Simplified version is n = 7
First find the rate of growth using the formula of
A=p e^rt
A 7200
P 6000
E constant
R rate of growth?
T time 6 hours
We need to solve for r
R=[log (A/p)÷log (e)]÷t
R=(log(7,200÷6,000)÷log(e))÷6
R=0.03 rate of growth
Now predict how many bacteria will be present after 17 hours using the same formula
A=p e^rt
A ?
P 6000
R 0.03
E constant
T 17 hours
A=6,000×e^(0.03×17)
A=9,991.7 round your answer to get
A=9992
2(30+x-6)-20

The total cost of hard drive is $29.96
Step-by-step explanation:
Given,
Original price = $40
Discount = 30%
Discount amount = 30% of $40 = 
Discount amount=
Price after discount = Original price - discount amount
Price after discount = 40-12 = $28
Tax rate = 7%
Tax amount = 7% of price after discount

Total cost of hard drive = Price after discount + Tax amount
Total cost of hard drive = 28+1.96 = $29.96
The total cost of hard drive is $29.96
