Oscar invests $20,000 in three investments earning 6% ,8% and 10%. He invests $9000 more in the 10% investment than in the 6% in
Hatshy [7]
This problem is mainly concerned with setting up an equation.

let's add the interest rates times their respective investment amounts:

a = (9000 + x)0.10

b = x \times 0.06

c=(20000 - ((9000 + x) + x)) 0.08

simplify:

c = (11000 - 2x) \times 0.08

sum of interest:

1780 = a + b + c

1780 = (9000+x) 0.10 + x 0.06 + (11000-2x)0.08

1780 = 1780 + 0 \times x

0=0

solution:

He does not have any invested in the 6%, while he has 9000 invested at 10% and 11,000 invested at 8%

to check:

9000 \times 0.10 + 11000 \times 0.08

= 900 + 880 = 1780

So this ended up being a trick problem because he does not actually have any invested in the 6% option.

Decompose a fraction equal to one whole
Soloha48 [4]

To decompose a fraction to one whole, there are different methods to use. The fraction can be decomposed either by division, multiplication(if there are more than one fraction), or addition(if there are more than one fractions).

Example:

Given 8/2, decompose by division:

To do this, divide the numerator by denominator

\frac{8}{2}=4
