Answer:
Step-by-step explanation:
So the initial value of the business computer is $20,000. It depreciates by 15% per year. This is exponential decay. The standard function for exponential decay is:
Where <em>P </em>is the initial value, <em>r</em> is the rate of decay, and <em>t</em> is the time in years.
Since the computer decreases by 15% per year, this means that each year, the computer will be 1-15% or 85% than its previous value.
Therefore, the equation that models the value of the computer is:
Answer:
3x - 20 = 5
Step-by-step explanation:
if there's 3 counselors / 45 students.
3 counselors / 45 students = 1 counselor / 15 student
10 counselors multiplied by 15 students = 150 maximum students allowed.
Tanya paints 55 ft^2 / 30mins.
60 mins = 1 hour
60 mins / 30 mins = 2
55 multiplied by 2 = 110
(There were two different people mentioned in the problem)
Tanya, or Angela, paints 110 square feet every hour.
