2) If Kyle put the whole of it into the 3% account, then she would get 20,000x3%=$600.
For however much she puts into the 5% account, she gets 5-3=2% more.
She got $760 and she gets $600 from the low rate, so she needs $160 more.
If it was all in the high rate account, she would get 20,000x2%=$400 more, but she only wants $160. (Don't know why, though)
This means that she puts 160/400=40% of her money, or $8,000, in the high account.
To summarise, $8,000 at 5% and $12,000 at 3%.
Sorry if I've just made this more complicated with my bad explanation.

Ok hello everyone and thanks for your time I need help with 2 things

2) Word Problem : Kyle invested $20 000, part in bonds that paid 3% annum and the remainder in term deposits that paid 5 per annum. The total interest after one year was $760. How much did she invest at each rate?
