We can set this up as a proportion.

Since 2 is proportional to 1000, then 4 is proportional to "doctors surveyed".

\frac{2}{4}  =  \frac{1000}{d} where d is the doctors surveyed.

Cross multiply.

2d = 4000
d=2000

2000 doctors were surveyed.

Sarawong's school is selling tickets to the annual talent show. On the first day of ticket sales the
SIZIF [17.4K]

Answer:

Price of the adult ticket is $13

Price of the child ticket is $3

Step-by-step explanation:

Lets x be the adult ticket and y be the child ticket.

Given:

School sold 14 adult tickets and 14 child tickets for a total of $224, so the first equation is.

14x+14y=224-------------(1)

And the school took in $44 on the  second day by selling 2 adult tickets and 6 child tickets, so the second equation is.

2x+6y=44---------------(2)

We find the price of an adult ticket and the  price of a child ticket by solving above system of equation.

Now, equation 2 multiplied by 7.

7(2x+6y=44)

14x+42y=308---------(3)

Now, equation 1 subtracted by equation 3.

14x+42y=308

14x+14y=224

-______________

14x is cancelled in both equations, so we get the equation.

28y=84

y=\frac{84}{28}

y = 3

Now, we substitute y = 3 in equation 2.

2x+6(3)=44

2x+18=44

2x=44-18

2x=26

x=\frac{26}{2}

x = 13

Therefore, the price of the adult ticket is $13 and the price of the child ticket is $3.
