Account balance with interest

Write a program to compute the new balance of a user's bank account when an interest rate $($a percentage$)$ is applied. Prompt the user for their starting balance and calculate the new balance of the account with the interest added in$.$ Assume the interest rate is stored in the variable interest$\_$rate.

Print the new balance of the account showing the new balance to two significant places $($do not attempt to set the overall width of the output $($ie: $\{$:$12\mathrm{.}3$f$\})).$ Your solution should match our output format and must use the format$)$ method.

Execution example:

What is the user's account balance $($a float$)?10\mathrm{.}04$

With interest, the new account balance is: $$10\mathrm{.}41$
