Zack bought a coat for $ 69.78 he paid with a $100 bill and received $26.73 in change. how much was the sales tax ?

The sales tax was $3.49.

First, you just subtract 69.78 from 100, and you get 30.22. Then you subtract 26.73 from 30.22 and you get 3.49.

Hope that helped!

the answer for this question is 38

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
