The cost of a new robotic toy after an 8% markup can be represented by the expression r+0.08r . Simplify the expression.

a negative exponent is translated as follows:

so, we have

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
