Answer:
Subtraction property of equality
Step-by-step explanation:
 c + 5 = 78
Subtract 5 from each side using the subtraction property of equality
c+5-5 = 78-5
x = 73

389 children and 224 adults were at the pool that day.
Step-by-step explanation:
Cost of one child ticket = $1.75
Cost of one adult ticket = $2.25
Total people = 613
Total receipts worth = $1184.75
Let, 
Number of children = x
Number of adults = y
According to given statement; 
x+y=613    Eqn 1
1.75x+2.25y=1184.75    Eqn 2
Multiplying Eqn 1 by 1.75

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 0.50

Putting y=224 in Eqn 1

389 children and 224 adults were at the pool that day.
