A sports club needs to raise at least $500 by selling chocolate bars for $2.50 each. Sebastian wants to know how many chocolate bars, c, the sports club must sell in order to reach its goal.

Which of the following must be true about the inequality and the resulting graph? Select three options.
The inequality should be written as 2.50 c greater-than-or-equal-to 500.
The inequality should be written as 2.50 c less-than-or-equal-to 500.
The circle is open.
The circle is closed.
The arrow points right.

The true options are:

-The inequality should be written as 2.50c less than or equal to 500.

-The circle is closed

-The arrow points right

Hope this helps!! :)

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

step-by-step explanation:

mark brainliest!

the answer is b
