Let's assume the amount invested at 8% per year is x dollars.
Then, the amount invested at 3% per year would be (35,500 - x) dollars.

The annual income from the investment at 8% would be x multiplied by 8% (or 0.08).
Similarly, the annual income from the investment at 3% would be (35,500 - x) multiplied by 3% (or 0.03).

Given that the total annual income is $2,740, we can set up the following equation:

0.08x + 0.03(35,500 - x) = 2,740

Let's solve this equation to find the value of x.

0.08x + 0.03(35,500 - x) = 2,740
0.08x + 1,065 - 0.03x = 2,740
0.05x + 1,065 = 2,740
0.05x = 2,740 - 1,065
0.05x = 1,675
x = 1,675 / 0.05
x = 33,500

Therefore, $33,500 is invested at 8% per year, and $35,500 - $33,500 = $2,000 is invested at 3% per year.

Answer: $33,500 is invested at 8% per year, and $2,000 is invested at 3% per year.

Which statement best describes the key changes in perspectives on inclusion? An inclusive program must consider the unique experiences of every child and family as well as the child's strengths and needs. There is a shift in thinking about individual programs as "inclusive programs" to thinking about inclusion as something that reflects the cultural influence of the family. There is a greater emphasis on barriers to full participation and the acknowledgement that all children are unique and must be fully and meaningfully engaged in a program. In an inclusive program all participants are accepted by their peers and other members of the community.
