70 adults and 100 children attended the carnival.
Step-by-step explanation:
Given,
Cost of each adult ticket = $10
Cost of each child ticket = $5
Total tickets sold = 170
Total revenue generated = $1200
Let,
Number of adults = x
Number of children = y
According to given statement;
x+y=170 Eqn 1
10x+5y=1200 Eqn 2
Multiplying Eqn 1 by 10

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 5

Putting y=100 in Eqn 1

70 adults and 100 children attended the carnival.

you do 42 devided by 6=7
The 17500 job will pay tax of (17500-5700-3650)=8150*0.10=815
The 18000 job will pay tax of 8350*0.10+300*0.15=880
The difference in pay is therefore 500-(880-815)=$435
D=-1
-15d=15 so -d=1 so d=-1
