Responses

y=78(0.03)x
y is equal to 78 times 0 point 0 3 to the x th power

y=78(1.03)x
y is equal to 78 times 1 point 0 3 to the x th power

y=78(0.97)x
y is equal to 78 times 0 point 9 7 to the x th power

y=78+1.03x
y is equal to 78 plus 1 point 0 3 x

foxes in the park.

1 answer

The correct exponential equation that models the situation of the fox population growing at a rate of 3% per year is:

y = 78(1.03)^x
(y is equal to 78 times 1.03 to the x-th power)

Now, to complete the statement for how many foxes will be in the park after 8 years, we can use the equation:

\[ y = 78(1.03)^8 \]

Calculating this:

  1. Calculate \(1.03^8\): \[ 1.03^8 \approx 1.26677 \]

  2. Now multiply it by 78: \[ y \approx 78 \times 1.26677 \approx 98.86 \]

Rounding to the nearest whole number gives:

After 8 years, there will be approximately 99 foxes in the park.
