I need help
an investor invested 1,200 in two funds. One fund earned a 7% profit and one earned a 2% profit. The total profit is 39$ so how much was invested in each acount

Answer 1

T + S = $1,200
.02T + .07S = $ 39
Can you solve it now?

Answer 2

let me see I might be a minute

Answer 3

.07+.02=.09, this is where I am stuck, finding the amount in the first acount

Answer 4

2T + 7S = 3900
How about now?

Answer 5

t+1950-7s/2

Answer 6

How about now?
2 ( 1,200 - S ) + 7S = 3900

Answer 7

what is the 3900 for?

Answer 8

dollars

Answer 9

got it

Answer 10

S = ? , T = ?

Answer 11

t=2

Answer 12

Do you know how to multiply?
2 ( 1,200 - S ) + 7S = 3900

Answer 13

yes but I have been stuck on this one for 3 hours. I see how you got 3900

Answer 14

I am missing part of the equation

Answer 15

which part are you missing???

Answer 16

I cannot figure out how to come up with the amount the fund that has 9%.. Can you show me what step I am missing?

Answer 17

There's nothing 9% !!!

Answer 18

how much was invested into the fund that had 7%. How much was invested into the fund that had 2% This is where I am lost. 1200 is split between 2 acounts

Answer 19

I can't figure this part out

Answer 20

Do you know how to multiply to obtain the amount 7%:
2 ( 1,200 - S ) + 7S = 3900

Answer 21

yes I used a calculator

Answer 22

Nothing to use calculator here!

Answer 23

3900 is the amount of profit

Answer 24

Are you capable of multiply by 2 * 1,200?

Answer 25

2*1,200=2400

Answer 26

Then, do it:
2 ( 1,200 - S ) + 7S = 3900

Answer 27

(1,200-S) looses me

Answer 28

Thank you very much for your patience and help. I need to leave this one alone for awhile.

Answer 29

I will save this so I can review

Answer 30

2 ( 1,200 - S ) + 7S = 3,900
2,400 - 2s + 7s = 3,900
-> s = ( 3,900 - 2,400) / 5 = 300
=> T = ...?
