Last year, Lucy deposited

$3000
into an account that paid
5%
interest per year and
$7000
into an account that paid
4%
interest per year. No withdrawals were made from the accounts.

What's the question?

Hello DJ have you done psychology the science of the mind. I checked you uploaded a question. If yes please answer

To find the total interest earned on Lucy's deposits, we need to calculate the interest earned from each account separately and then add them together.

Let's calculate the interest for each account first.

Account 1:
Principal amount (P1) = $3000
Interest rate (R1) = 5%
Time (T1) = 1 year

The formula to calculate the interest is:
Interest (I1) = P1 * R1 * T1

Substituting the values, we get:
I1 = $3000 * (5/100) * 1

Simplifying the expression, we have:
I1 = $150

So, the interest earned from Account 1 is $150.

Account 2:
Principal amount (P2) = $7000
Interest rate (R2) = 4%
Time (T2) = 1 year

Using the same formula to calculate the interest, we have:
I2 = $7000 * (4/100) * 1

Simplifying the expression, we get:
I2 = $280

So, the interest earned from Account 2 is $280.

Now, to find the total interest earned, we sum up the interest from both accounts:
Total interest earned = I1 + I2
Total interest earned = $150 + $280
Total interest earned = $430

Therefore, the total interest earned on Lucy's deposits is $430.
