PART A A bicycle shop marks down each bicycle price b, by 34% for a holiday sale. Write an algebraic expression that describes the sale price of the bicycle.

PART B Use your expression to determine the cost of a $400 dollar bicycle.

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
