Using the percentage, the amount raised in the first three month is $840
<h3>How to find the amount raised in 3 months?</h3>
The Helping Hands Student Club set a goal to raise $3,000 by the end of the school year for a project.
After 3 months, it reaches 28 percentage of its goal.
The amount that was raised during the first three months can be calculated as follows:
amount raised = 28% × 3000
amount raised = 28 / 100 × 3000
amount raised = 84000 / 100
Therefore,
the amount raised in the first three month = $840
