D=4n-2, d+2=4n-2+2, d+2=4n
(d+2)/4=(4n)/4, 1/4d+1/2=n
n=1/4n+1/2

size 3=
n=1/4*3/1=3/4, 3/4+1/2=5/4=1 1/4
size 3=1 1/4

size 6=
n=1/4*6/1=6/4, 6/4+1/2=8/4=2
size 6=2

size 10=
n=1/4*10/1=10/4, 10/4+1/2=12/4=3
size 10=3

Answer:

The penny size d is given by the literal equation d=4n-2

Where n is the length (in inches) of the nail.

We can deduce the value of n from equation above:

(d+2)/4=n

Now we have to find n with various values of d.

1. when d = 3 inches

n=(3+2)/4

=>n=5/4

n = 1.25 inches

2. when d = 6 inches

n=(6+2)/4

=>n=8/4

n = 2 inches

3. when d = 10 inches

n=(10+2)/4

=>n=12/4

n = 3 inches
