Final answer:
The percent decrease when the balance in a bank account goes from $300 to $240 is 20%.
Step-by-step explanation:
To find the percent decrease, we need to calculate the difference between the initial balance and the final balance, which is $300 - $240 = $60. Then, we divide the difference by the initial balance and multiply by 100 to get the percent decrease. In this case, (60/300) x 100 = 20%. Therefore, the percent decrease is 20%.
