x+4=20 is a solution to 5(x+4)=100.

Nina decided to raise money for a community organization that provides free classes and legal
Over [174]

A percentage is a way to describe a part of a whole. The money that is raised by Nina in the second month is $960.

<h3>What are Percentages?</h3>

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given that the money raised by Nina in the first month is $800, while the money raised by Nina in the second month is 20% more.

Therefore, the money raised by Nina in the second month is,

Money raised = $800 + 20% of $800

                       = $800 + 0.20($800)

                       = $800 + $160

                       = $960

Hence, the money that is raised by Nina in the second month is $960.
