The school that maria goes to is selling tickets to a musical performance. on the first day of tickets sale the school sold 10 adult tickets and 3 child tickets for a total of $245. the school took in $115 on the second day by selling 5 adult tickets and 1 child ticket,

Adult tickets cost $20, child tickets cost $15

Step-by-step explanation:

I'm going to assume that we have to say how much the tickets cost

x- cost of an adult ticket

y- cost of a child ticket

10x+3(115-5x)=245

10x+345-15x=245

-5x=-100

x=20

y=115-5*20=15

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
