A school fair is selling tickets. On the first day they sell 1 adult ticket and 4 child tickets to make $63. On the second day they make $105 by selling 3 adult tickets and 5 child tickets. How much do adult tickets cost? How much are child tickets? (Pls show work)

1 adult ticket costs $9.45

1 child ticket cost $3.15

Step-by-step explanation:

63/5 = 12.6

12.6/4 = 3.15

12.6 - 3.15 = 9.45

I think this is correct if not search up

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

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!
