9. Bettina bought and socks for $23.20. Nancy bought to pairs of socks for $30.00
Who got the stter deal? (Hint Find unit rate for each)

answer:

Nancy

Step-by-step explanation:

Bettina bought one pair of socks for $23.20

If Nancy bought two pairs of socks for $30.00, that means that each one cost $15.00 (30/2).

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
