C. Quadratic. The graph is a parabola
The answer is 93 It’s 1209 divided by 13 not 13 divide by 1209 ;) hope this helps ! Because when we’re dividing the number get smaller and when we multiplying the number gets bigger , have a nice day !
if the graph is NOT a linear function, then the two variables are NOT directly proportional
Let
C=child ticket
A=adult ticket
then
A=C+8 ........(1)
and
7A+2C=173 ......(2)
Substitute (1) in (2)
7(C+8)+2C=173
distribute
7C+56+2C=173
isolate C and solve
9C=173-56=117
C=$13
hence adulat
A=$13+$8=$21.
