Substiture b for 50 and h for 20 so
(50)(20)
1000/2
A = 500
It's the first one. y can equal x as long as y doesn't equal x multiple times. We also know the last two are wrong because they're saying the same thing. A linear function is a straight line.
Since the question is asking how many pencils the teacher will have to give out, we can automatically ignore the 46 erasers from the problem because it is not relevant. The information was most likely put there to confuse you.
Each student is getting 28 pencils, so if we multiply the number of students by 28 pencils, we will find how many pencils the teacher will need to give out.

42 * 28 = 1,176
The teacher will have to give out <u>1,176 pencils</u> to her 42 children in the classroom.
