We are told that $168.00 represents 8% of the contract price; therefore,we know that
original price *( 8/100) = $168.00
Now, writing out "original price" is a bit space-consuming; therefore, we will just rename it and say
original price = OP
Then, our equation above can be written as

We solve for OP (original price) by multiplying both sides by 100 and then dividing by 8. This gives us


Hence, the original contract price is $2100.
Answer:
18 miles
Step-by-step explanation:
<u>Let </u>
- The number of miles = x .
<u>According</u><u> to</u><u> Question</u><u> </u><u>,</u>
- 100 + 0.5(x) = 40 + 0.8(x)
- 100 + 0.5x = 40+ 0.8x
- 100 - 40 = 0.8x - 0.5x
- 60 = 0.3x
- x = 60/3 * 10
- x = 18

Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x ----> the number of open acres
y ----> the number of developed acres
we know that
-----> inequality A
The solution of the inequality A is the shaded area above the solid line 
-----> inequality B
The solution of the inequality B is the shaded area below the solid line 
so
The graph in the attached figure
I use a bit of a different looking formula.
A(t)=P(1+r/n)^nt
P=amount of money. (500)
r= rate (in decimal. 4%=0.04)
n=number of times per year (1 in this problem)
t=amount of time. (5 years)
Plugged in it looks like this:
A(t)=500 (1+ 0.04/1)^1x5
Then I put it into my calculator like this:
0.04/1+ 0.04
Then add one to the above answer:
0.04+1=1.04
Then raise the above answer to the 1x5:
1.04^5=1.2166......
Then multiply the above answer by 500:
1.2166.... x 500=608.3264512
She has $608 after 5 years.
Hope this helps, let me know if you have any questions.
