There were n signers of the Declaration of Independence. The youngest was Edward Rutledge, who was x years old. The oldest was B
enjamin Franklin, who was y years old. X is 25% of 104, 7 is 10% of y, and n is 80% of y. Y is what percent of (n+y-x)?
2 answers:
X = .25 x 104 X=26
Y= 7/.10 Y=70
N= .8 x 70 N=56
n+y-x 56+70-26=100
70/100 = .7 or 70%
The answer is: Y is 70% of (n+y-x)
Answer:
70%
Step-by-step explanation:
First we calculate X using the following formula:
X = 25/100 * 104
X = 0.25 * 104
X = 26
Then we calculate Y using the following formula:
7 = 10/100 * Y
7 = 0.1 * Y
7/0.1 = Y
Y = 70
Then we calculate N as per the formula below:
N = 80/100 * Y
N = 0.8 * 70
N = 56
Finally using the formula mentioned in question we derive Y what percent of N + Y - X:
= Y/ (N + Y - X) * 100
= 70/ (56 + 70 - 26) * 100
= 70/100 * 100
= 70%
