Answer:
$73.60
Step-by-step explanation:
Original price: $64
Markup: 0.15($64) = $9.60
New retail price: $64 + $9.60 = $73.60
The reasoning of Frank is not correct. The value of 5 is the thousandths place is 1/10 times the value of 5 in the hundredths place instead of being 10 times.
In the question, we are given the number 0.555.
We can write it as:-
0.555 = 0.500 + 0.050 + 0.005
0.500 is the value of tenths place
0.050 is the value of hundredths place
0.005 is the value of thousandths place
We know that,
0.050*(1/10) = 0.050/10 = 0.005
Hence, the value of 5 is the thousandths place is 1/10 times the value of 5 in the hundredths place.

Direction vector of line of intersection of two planes is the cross product of the normal vectors of the planes, namely
p1: x+y+z=2
p2: x+7y+7z=2
and the corresponding normal vectors are: (equiv. to coeff. of the plane)
n1:<1,1,1>
n2:<1,7,7>
The cross product n1 x n2
vl=
i j l
1 1 1
1 7 7
=<7-7, 1-7, 7-1>
=<0,-6,6>
Simplify by reducing length by a factor of 6
vl=<0,-1,1>
By observing the equations of the two planes, we see that (2,0,0) is a point on the intersection, because this points satisfies both plane equations.
Thus the parametric equation of the line is
L: (2,0,0)+t(0,-1,1)
or
L: x=2, y=-t, z=t
The answer to the question is a) -4.
