Jill and brian divided up $1900 between two investment accounts. jill's account earns 4% interest and brian earns 3%. if their combined interest earns them $70, then how much was originally invested in each account?

The amounts invested in the accounts that yielded 3% and 4% interests are $600 and $1,300 respectively

Explanation:

Total amount divided = $1900

Let the amount invested in the two accounts be a and b

such that

a + b = 1900       Equation 1

then,

3% of a + 4% of b = 70

0.03a + 0.04b = 70

3a + 4b = 7000    Equation 2

Solving equations 1 and 2 simultaneously

a + b = 1900

3a + 4b = 7000

3a + 3b = 5700

b = 7000 - 5700

b = 1,300

a = 1900 - 1300

a = 600

The amounts invested in the accounts that yielded 3% and 4% interests are $600 and $1,300 respectively.

if you use only 25 for your entertainment and only 200 for the groceries that you really need and take out the 50 per month for the computer then that should be enough
