Answer:
12 adults
Step-by-step explanation:
If a child ticket costs 5 dollars
then 125-5=120
120 divided by 10(the cost of each ticket for an adult)
12
So there are 12 adults
125 - 5 = 120 (this is subtracting the child from the equation)
120 / 10 = 12
Answer: 4(−a+1)(a−1)
the answer would be B 21.7
315 and 128
