Answer:
$5,500
Step-by-step explanation:
Let A be the amount invested at 3%, B the amount at 4%.
Total value:
1.A%2BB=8000
Interest:
Multiply eq. 1 by -3 and add to eq. 2,
-3A-3B%2B3A%2B4B=-24000%2B29500
highlight%28B=5500%29
Then from eq. 1,
A%2B5500=8000
highlight%28A=2500%29
Answer:
b.
Step-by-step explanation:
The factors of 48 are:
1 x 48
2 x 24
3 x 16
4 x 12
6 x 8
and visa versa: 48 x 1 etc.
To make the product negative, one of the factors has to be positive and one has to be negative. To find the greatest sum, make the bigger number the positive factor and the smaller number the negative factor. So, -1 x 48 = -48 and the sum of -1 + 48 = 47 which would be the greatest possible sum.
