Question

Erika is renting an apartment. The rent will cost her $1,450 per month. Her landlord will increase her rent at a rate of 3.2% per year. Which of the following are functions that model the rate of her rent increase? Select all that apply.

A. y = 3. 2(x - 1) + 1,450 0
B. y = 1,450-1. 0327-1
C. y = 1,450-1.032
D. y = 3.2x + 1,418 0
E. y = 1,405-1.032*
F. y = 46. 4(x - 1) + 1,450

Answer 1

The functions that model the rate of Erika's rent increase are:

B. y = 1,450(1 + 0.032x)

C. y = 1,450(1.032)^x

Note: Option B uses the formula for compound interest, where the initial amount (principal) is $1,450, the annual interest rate is 3.2%, and x is the number of years. Option C uses the same formula but with the interest rate expressed as a decimal (1.032) raised to the power of x, which represents the number of years.

I hope this helps you!
