In order to use the simple interest formula, we first define the variables. The interest would be equal to Samuel's desired amount $ 2,488 minus the principal amount of $ 1,800 which is then equal to $ 688. The rate must be in decimal form which is equal to 0.12 while t is expressed in years. Substituting the values, t is equal to 3. Thus, it will take 36 <span>months for Samuel's account balance to reach $2,448. </span>
The answer is 6.89 because
6.89+14.52=21.41
So 21.41+(-14.52)=6.89
Imposible triangle, lagest side must be > sum other sides.
T(n) = 0.2n
