1 is 28
2 is 13, 84, 85
Figure both by the Pythagorean Theorem<span />
Answer: Look below
Step-by-step explanation:
10% = $120.90
1% = $12.09
11% = $132.99
$1,209 + $132.99 = $1,341.99
She made a $132.99 profit or $1,341.99
—————————————————————
8% = 96.72
$1,341.99 - $96.72 = $1245.27
————————————————
Or if it is $96.72 off the price she bought it then it would be
$1,209 - $96.72 = $1,112.28
For this case, the first thing we must do is define variables.
We have then:
x: amount of money for charity 1.
y: amount of money for charity 2.
We now write the system of equations that models the problem:
We solve the system.
Using substitution we have:
Clearing x:
Then, the value of the second charity is:
Answer:
charity 1 = $ 83500
charity 2 = 65500 $
The right answer is √47
all the others are perfect squares
