To determine how much the Johnsons would have in the account after one year if they put all their monetary assets ($10,660) into a money market account earning 2.4% interest, we can use the formula for simple interest (since compound interest isn't specified here):

$A = P(1 + r)$

Where:

• $A$ is the amount in the account after one year.
• $P$ is the principal (initial deposit), which is $10,660.
• $r$ is the annual interest rate, which is 2.4% or 0.024.

Substitute the values into the formula:

$A = 10,660(1 + 0.024)$ $A = 10,660 \times 1.024$ $A = 10,916.18$

After rounding to the nearest dollar, the Johnsons would have $10,916 in the money market account after one year.
