A new bank customer with ​$4,000 wants to open a money market account. The bank is offering a simple interest rate of 1.2​%. a. How much interest will the customer earn in 30 ​years?
b. What will the account balance be after 30 ​years?

Interest: $1440

Total Account Balance: $5440

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 1.2%/100 = 0.012 per year,

then, solving our equation

I = 4000 × 0.012 × 30 = 1440

I = $ 1,440.00

The simple interest accumulated

on a principal of $ 4,000.00

at a rate of 1.2% per year

for 30 years is $ 1,440.00.

The answer is 1,440 (sorry if it's wrong)

Explanation:  

You multiply 4,000 by 1.8% which u will get 72 then multiply 72 by 20 and then that will get you 1,440.

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
