Answer:
The amount invested at 6% is $12,857.14
The amount invested at 13% is $17,142.86
Step-by-step explanation:
Let
x ----> the amount invested at 6%
30,000-x -----> the amount invested at 13%
we know that
The interest earned by the amount invested at 6% plus the interest earned by the amount at 13% must be equal to the interest earned by the total amount of $30,000 at 10%
Remember that
so
The linear equation that represent this situation is
solve for x
therefore
The amount invested at 6% is $12,857.14
The amount invested at 13% is $17,142.86
Answer:
18,920.00
Step-by-step explanation:
discount = x
original price = $20,000
discount% = 5.4%
x/20,000 = 5.4/100
x · 100 = 5.4 · 20,000
100x = 108,000
100x/100 = 108,000/100
x = $ 1,080.00
Sale price = original $ - discount $ = final answer
$20,000 - $1,080 = $18,920.00
You start by cross multiplying:
9 x 8 = 72
This is considered the fraction on the left's value.
You do the same for the other side:
10 x 7 = 70
This is considered the value of the fraction 7/8
72 has a greater value than 70.
Therefore, 9/10 is larger.
