Pit this in your calculator exactly like this 4,000(1.05)^5 and you get the answer 5,105.12625. So round your answer to the nearest dollar, which is 5,105.
Hi there!
Mrs. Miller earns a commission of 6% of 179,000
The word "of" is the same thing as a multiplication sign.
6% of 179,000 = 6% × 179,000
6% = 0.06
6% × 179,000 = 0.06 × 179,000
0.06 × 179,000 = 10,740
Your answer is: Mrs. Miller earns $10,740 of commission.
There you go! I really hope this helped, if there's anything just let me know! :)

Valarie make 
of fruit drink.
Step-by-step explanation:
Given:
Valarie made fruit drinks for a birthday party.
She used 3/6 of a cup of grape juice, 5/6 of a cup of strawberry juice, and 2/6 cup of soda. She mixes all the juices together.
Now, to find cups of fruit drink Valarie make.
As given that she mixes all juices altogether.
So, to get the cups of fruit drink we add all quantities of juice:
3/6 cup of grape juice + 5/6 cup of strawberry juice + 2/6 cup of soda.
<em>Dividing numerator and denominator by 2 we get:</em>
Therefore, Valarie make of fruit drink .
Answer:
x = 2, y= 3
Step-by-step explanation:
y = -2x+7
y = 5x-7
Since the equations are both equal to y, set them equal to each other
-2x+7 = 5x-7
Add 2x to each side
-2x+7 +2x= 5x+2x-7
7 = 7x -7
Add 7 to each side
7+7 = 7x
14 = 7x
Divide by 7
14/7 = 7x/7
2 = x
Now find y
y = 5x-7
y = 5*2 -7
y = 10-7
y =3
