Cooper saved $302.40 in April.
The bar graph you sent me shows Cooper's savings for March, April, and May. The question asks how much Cooper saved in April, given that he saved three times as much in April as he did in March, and that he saved a total of $504 during these months.
To solve this, we can let X represent the amount Cooper saved in March. We know that he saved 3X in April and that the total amount he saved for all three months is $504.
Therefore, we can set up the following equation:
X + 3X + X = $504
Combining like terms, we get:
5X = $504
Dividing both sides by 5, we get:
X = $100.80
Therefore, Cooper saved $100.80 in March. Since he saved 3 times as much in April, he saved 3 * $100.80 = $302.40 in April.
So the answer to the question is: Cooper saved $302.40 in April.
