Number 1 is 12.

Step-by-step explanation:

{Solve by cross multiplication}

17 • x = 3 • (80 - x)

{Multiply 3 by distribution,}

17x = 240 - 3x

{Add 3x to both sides of the equation,}

20x = 240

{Divide through out by 20,}

20r/20 = 240/20

x = 12

Thus there were 12 pens :)

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

this doesn't make sense lol
