Answer:
There would be 8 red marbles and 47 purple marbles.
Step-by-step explanation:
In order to find this, we can first set the amount of red marbles as x. Once we do this, it is possible to model the number of purple marbles as 5x + 7. Knowing this, we can add the two together and set equal to 55.
x + 5x + 7 = 55
6x + 7 = 55
6x = 48
x = 8
With 8 red marbles, we know the rest must be purple (47)
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
