A school held a charity concert over two days, collecting $2,400 the first day and $1,400 the second day. The system of equations 250 x plus 100 y equal 2 comma 400 spaceand 150 x plus 50 y equal 1 comma 400 can be used to determine x, the cost of an adult ticket, and y, the cost of a child ticket. Use the multiplication property of equality to rewrite the system so that the coefficients of the variable y are the same for both equations.
Find the cost of an adult ticket and the cost of a child ticket.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

the answer will be
