The equation p= 2.5m + 35 represents the price p of a bracelet, where m is the cost of the materials. The price of a bracelet is
Klio2033 [76]
P= 2.5m + 35    (replace p with 115)
115= 2.5m + 35  (subract 35 from each side)
115 - 35 = 2.5m
80 = 2.5m    (divide 2.5 from each side)
80/2.5= 2.5m/2.5
32 = m

The price of the materials is $32

Answer:

<em>Option B</em>

Step-by-step explanation:

<u>Congruent Triangles</u>

The SAS Similarity Theorem states that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both triangles are congruent, then the two triangles are similar.

The triangles \Delta LKN\ and\ \Delta KNM are congruent if the relation between LK and KN is the same as the relation between KN and MN, that is

\displaystyle \frac{4}{2}=\frac{2}{MN}

It means that

MN=1

Option B
