tekilochka [14]
In the given problem, it is given that the table is sold at a discount of only one day and that is today. so the table would be have been sold at its original price yesterday. The discount given today is 34% and the sale price for today is $495.
Let us assume the price of the table yesterday = x
Then we can write the equation as
x = 295 * (100/34)
  = 29500/34
  = 867.64
So the selling price of the table yesterday was $867.64.

1) Which equation could be used to estimate the population of Oak City in 10 years?
DaniilM [7]

Answer:

1) A

2) B

Step-by-step explanation:

For this problem we use exponential growth formulas

y = y_0(1 + r) ^ t if the population increases when t increases

y = y_0(1-r) ^ 2 If the population decreases when t increases

Where and is the population as a function of time, y_0 is the initial population, r is the growth rate, t is the time in years.

1) In this situation we have that y_0 = 48000, the growth is 2.4%, then r = 0.024 and t = 10 and the equation is:

y = 48000(1 + 0.024) ^ {10}

y = 48000(1.024) ^ {10} -------- Option A)

2) In this situation we have that y_0 = 82000, the decrease is 1.7%, then r = 0.017 and t = 5 and the equation is:

y = 82000(1-0.017) ^ 5

y = 82000(0.983) ^ 5 -------- Option B)
