Suppose Becky invests in an annuity that pays 4.3% annual interest, compounded monthly and contributes $225 every month for 20 years. She wants to calculate the value at the end of the 20 years and does so using the following computation:

$85365.90

Step-by-step explanation:

Let's start by finding the effective rate of interest

.043/12=.00385333

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
