Answer:
26 child tickets
Step-by-step explanation:
4c = a to make the adult tickets equal to the child tickets multiply the child tickets by 4. then use substitution.
6.10c + 9.90(4c) = 1188.20
6.10c +39.6c = 1188.20
45.7c = 1188.20
c = 26
To find the x-intercept set y=0 and solve for x.
3x-7y=21
3x-7(0)=21
3x=21
x=7
so, x-intercept is at (7,0)
to find the y-intercept set x=0 and solve for y.
3x-7y=21
3(0)-7y=21
-7y=21
y=-3
so, y-intercept is at (0,3)
