Answer:
15%
Step-by-step explanation:
Given,
Original price = $55.00
Discounted price = $46.75
Discount = $55.00 - $46.75 = $8.25
Percent Discount = (Discount / Original price) x 100%
= (8.25 / 55.00) x 100%
= 0.15 x 100%
= 15%
Answer:
9,942 bacteria were there at 10 hours.
Step-by-step explanation:
Equation for population decay:
The equation for population decay, after t hours, is given by:
In which P(0) is the initial population and r is the decay rate, as a decimal.
Researchers recorded that a certain bacteria population declined from 200,000 to 900 in 18 hours.
This means that and that when . So we use this to find r.
So
At this rate of decay, how many bacteria was there at 10 hours?
This is P(10). So
Rounding to the nearest whole number:
9,942 bacteria were there at 10 hours.
