Answer:
$87.5
Step-by-step explanation:
Original price also means COST PRICE
C.P=$50
S.P=75% of $50-$50
To find the sale price it will be 75% of C.P -C.P
75% × $50 + $50= 0.75 × $50-$50
=$37.5-$50.
= $12.5
therefore the sale price is $12.5

I + 6 = r
4r = s
i + r + s = 126
4i + 24 = 4r
s= 4r
i = r-6
4i+24=i+6
-3i=18
i = 6
Solve the rest
Hello!
Answer:$295.295
Explanation:
Of the statement, we have that the price of the machine decreased 10% every year
exponentially, so in the first year it real value drops to 90% of the costs. For 5 years, It can be expressed and simplified by the following equation:
We can't use that the percent drop as a percent itself, so we are going to divide 90% by 100%, and it will give us an entire number.

By substituting we have:

Value: $295.245
Have a nice day!

Answer:
Step-by-step explanation:
The answer is actually
Let:
S=1+2+3+4+5+6+7+8+9+n
We know the answer to the following infinite sum:
S2=1-1+1-1+1-1+1-1+1-1+1-1+1-....= - 1/2
We can therefore solve for this sum:
S3=1-2+3-4+5-6+7-8+9-....
We add them:
S3= 1-2+3-4+5-6+7-8...
S3= +1-2+3-4+5-6+7-8...
________________
2S3= 1-1+1-1+1-1+1-1+1-....
Therefore:
2S3=S2=
