Answer:
6.125 acres.
Step-by-step explanation:
We have been given that a builder buys 24.5 acres of land to develop a new community of homes and parks. The builder plans to use 0.25 of the land for a park.
To find the number of acres used for park, we will multiply total land by 0.25
Therefore, the builder will use 6.125 acres of land for the park.

Answer:
This is the same as writing y = 650(0.907)^t
=====================================================
Explanation:
Exponential equations can be of the form y = a*b^t
- a = initial amount
- b = growth or decay factor
In this case, we have
- a = 650 mg to start with
- b = 1 - 0.093 = 0.907 as the decay factor
If we had exponential growth, then we'd compute 1 + 0.093 instead.
Based on those values, we go from y = a*b^t to y = 650(0.907)^t which is the same as writing
Other exponential forms are possible, but I think this form is the most intuitive. The 0.907 means that 90.7% of the sample remains after each year.
