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
Since the answer after dividing 9 to the 7th power and 9 to the 5th power, 81 would be 9 to the 2nd power
so,
9^2
Y = 3x - 1
The slope is 3, y goes up 3 for every increase in x
The intercept point of the Y axis is -1
