At the movie theatre, child admission is $6.30 and adult admission is $9.60. On Monday, three times as many adult tickets as child tickets were sold, for a total sales of $1017.90. How many child tickets were sold that day?
Number of child tickets:

7 Child Tickets

Step-by-step explanation:

9.60 * 3 = 28.80

28.80 + 6.30 = 35.10

1017.90 / 35.10 = 29

29 / 4 = 7.25 = 7

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
