Tickets for a school carnival cost 10$ for adult and 5 for children. last Saturday carnival sold 170 tickets worth a total of $1

riadik2000 [5.3K]

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

$10(x+y=170)\\10x+10y=1700\ \ \ Eqn\ 3$

Subtracting Eqn 2 from Eqn 3

$(10x+10y)-(10x+5y)=1700-1200\\10x+10y-10x-5y=500\\5y=500$

Dividing both sides by 5

$\frac{5y}{5}=\frac{500}{5}\\y=100$

Putting y=100 in Eqn 1

$x+100=170\\x=170-100\\x=70$

70 adults and 100 children attended the carnival.

I’m having a crisis so please help 7x-19<16

vampirchik [111]

Answer:

5 i believe correct me if im wrong

Step-by-step explanation:

To work this problem out you would do it as if it were just a simple equation

7x-19<16 (you would first have to add 19 to both sides)

7x<35 (then you would divide by 7 to get the variable by itself)

x<5 ( you answer would then be 5)
