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.

Answer 1

Answer:

$2.50 times c is greater than or equal to c.

Step-by-step explanation:

Answer 2

Answer:

The inequality should be written as $2.50 times c is greater than or equal to c.

Step-by-step explanation:

First, identify what you know:

1) Each chocolate bar is $2.50

2) Sebastian needs to raise at least $500

So, Sebastian needs to sell at least enough chocolate bars to hit $500. The inequality cannot be written as less than or equal to, because he can't sell less than the number of chocolate bars needed to make $500.

Automatically, I can calculate the minimum number of bars he'll need to sell.

500/2.50 = 200 chocolate bars minimum

c must equal greater than or equal to $500, for Sebastian to raise enough money! So, basically Sebastian has to sell 200 bars OR more.

Hope this helps! :)
