Every seat that is sold in the auditorium costs 8 dollars. in addition to that, the auditorium makes 300 dollars as a flat rate. if the auditorium made $2772.00 dollars, how many seats were sold?

309

Step-by-step explanation:

8x + 300 = 2772

subtract 300 from both sides of the equal sign

8x = 2472

divide 8 from both sides of the equal sign

x = 309

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
