Respuesta :

Solution: $ 7,986

Analysis:

We have an initial value of $ 6,600. According to the exercise, that amount increased by 21%. So, we need to find the new value including the increment.

We use the formula:

[tex]\begin{gathered} Final\text{ }value=Initial\text{ }value\ast(1+increase\text{ }in\text{ }decimal) \\ Final\text{ }value=6,600\ast(1+0.21)=6,600\ast(1.21) \\ Final\text{ }value=7,986. \end{gathered}[/tex]
