AMDM Unit 4 Test

Sophia is comparing two investment options for a 10-year period:

• Option 1: A savings account that compounds interest annually at a rate of 6%.

• Option 2: A certificate of deposit that offers a fixed return of $500 per year.

• Based on these options, which function represents the value of the savings account after x years if the initial investment is $1,000?

• y=1000(1+0.06)^x

• y=1000+500x

• y=1000(1+0.06x)

• y=500x

Sophia is comparing two investment options for a 10-year period:

Option 1: A savings account that compounds interest annually at a rate of 6%.

Option 2: A certificate of deposit that offers a fixed return of $500 per year.

Which of the following correctly describes the comparison between the two investments after 10 years?

• The certificate of deposit will always have a higher total value.

• The savings account grows faster and will eventually surpass the certificate of deposit.

• Both investments will have the same total value after 10 years.

• The savings account grows linearly, while the certificate of deposit grows exponentially.
