Answer:
d ≥ 85 ; < - - - - - - - [85------------>
Step-by-step explanation:
d = how much more they have to raise
so the student council has raised $415 so far and their goal is $500, which can be expressed as the following inequality:
415 + d ≥ 500
in order to find out what d is, we solve the inequality by subtracting 415 from 500
500 - 415 = 85
so, they need $85 or more to complete their goal, which is why a greater than or equal to sign was used
the inequality can be expressed as: d ≥ 85, as we want $85 or more.
on a number line it would look similar to this:
< - - - - - - - [85------------>
the number 85 would have a closed circle or a bracket on it, and numbers greater than 85 would be shaded to the right
