Tickets were sold at a school play. adult tickets cost $4 and child tickets cost $2. they sold 930 tickets that day and they took in $2670. write and solve a system of equations to represent the situation.

see explanation

Step-by-step explanation:

Let a represent adults and c children, then

a + c = 930 → (1)

4a + 2c = 2670 → (2)

Multiply (1) by - 2 to eliminate the term in c when added to (2)

- 2a - 2c = - 1860 → (3)

Add (2) and (3) term by term

2a = 810 ( divide both sides by 2 )

a = 405

Substitute a = 405 into (1) and solve for c

405 + c = 930 ( subtract 405 from both sides )

c = 525

That is 405 adult and 525 children's tickets were sold

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
