Agroup of students must collect at least $120 to organize a science fair. they have already collected $30. which graph best represents all remaining amounts of money, in dollars, that the students should still collect to organize the science fair?

number line graph with closed circle on 120 and shading to the right

number line graph with closed circle on 90 and shading to the right.

number line graph with closed circle on 150 and shading to the right

number line graph with closed circle on 30 and shading to the right.

The correct option is 2.

Step-by-step explanation:

It is given that a group of students must collect at least $120 to organize a science fair. They have already collected $30.  

Let the remaining amounts of money, in dollars, that the students should still collect to organize the science fair be x.

Subtract 30 from both the sides.

It means the remaining amounts of money is greater than or equal to 90.

Therefore the number line graph with closed circle on 90 and shading to the right and option 2 is correct.

square root
