Step-by-step explanation:
we have
![13*[4+(9-2)]](https://tex.z-dn.net/?f=13%2A%5B4%2B%289-2%29%5D)
step 1
Solve 

substitute
![13*[4+7]](https://tex.z-dn.net/?f=13%2A%5B4%2B7%5D)
step 2
Solve ![[4+7]](https://tex.z-dn.net/?f=%5B4%2B7%5D)
![[4+7]=11](https://tex.z-dn.net/?f=%5B4%2B7%5D%3D11)
substitute
![13*[11]](https://tex.z-dn.net/?f=13%2A%5B11%5D)
step 3
Solve 

therefore
![13*[4+(9-2)]=143](https://tex.z-dn.net/?f=13%2A%5B4%2B%289-2%29%5D%3D143)
Answer:
A.
Step-by-step explanation:
4 < 6t + 1 ≤ 43 (Given)
3 < 6t ≤ 42 (Subtracted 1 on both sides)
1/2 < t ≤ 7 (Divided 6 on both sides)
You are looking for an open dot on 1/2 and a shaded dot on 7 with a line between them. Therefore, the answer is A.

Adult ticket (a) = $5
Child ticket (c) = $2
785 tickets = $3280
a + c = 785 tickets
5a + 2c = $3280
c = 215 child tickets
a = 570 adult tickets
570 + 215 = 785 tickets
5(570) + 2(215) = $3280
There were 215 child tickets sold on Saturday
