Given:

The original amount = $6600.

Interest = 21 %.

Aim:

We need to find the year-end amount.

Step-by-step explanation:

a)


We\text{ know that year-end amount = original amount+21 \% of the original amount.}


Y\text{ear-end amount = original amount+}(21)/(100)\text{ }*\text{original amount.}


Y\text{ear-end amount = original amount+0.21 }*\text{original amount.}

Take out the common term that is the original amount.


Y\text{ear-end amount = }(\text{ 1+0.21 })*\text{original amount.}


Ye\text{ar-end amount = }(\text{ 1.21 })*\text{original amount.}


Y\text{ear-end amount = 1.21 }*\text{original amount.}

b)


Y\text{ear-end amount = 1.21 }*\text{original amount.}

Substitute original amount = $6600 in this equation.


Y\text{ear-end amount = 1.21 }*6600


Y\text{ear-end amount = \$ 7986}

Final answer:


Y\text{ear-end amount = 1.21 }*\text{original amount.}


Y\text{ear-end amount = \$ 7986}
