Question

A group of students must collect at least $160 to organize a science fair. They have already collected $20. Which graph best represents the possible amounts of money the students still need to collect?

This is a mathematics question, for middle school.


Is it
A.
B.
C.
or D.

Answer 1

c the gragh shows how much more they need and its perfect for them.

Answer 2

The graph needs to represent the amount of money the students still need to collect. To find this out we would subtract the total needed by the amount already collected.

160 -20 =140

The students still need to collect $140.

The correct graph would be B the second one.

The students need to collect AT LEAST $160 meaning they can collect more than $160.

Hope this helps!
