Asports 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.

Step-by-step explanation:

The sports club sells $2.50 each bar of chocolate.

They need to reach at least $500.

The expression that models this situation is

Where is the number of chocolate bars.

Observe that we use the sign , that is because the problem specifies that "at least" the need $500, which is a minimum restriction.

Let's solve for

Therefore, they need to sell at least 200 chocolate to have at least $500.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
