Question 1057062: This is a linear equation word problem. The students store sells candy at a specific price but must purchase the candy in bulk once at the beginning of the month.
After the first day, the store has sold 10 pieces of candy but the store's profit is $-312.50.
After the last day of the month, the store has sold 375 pieces of candy and the store's profit is now $143.75.
Using your understanding of linear functions, determine how many pieces of candy the student store sold to break even (when profit is equal to$0.00). Explain how you arrived at your answer using complete sentences and/or mathematical equations and symbols.

Question 1058188: These assignments will prepare you for your career in Criminal Justice, Business, Human Resources, Finance, and Health Management because they are like procedures performed in the workplace. For instance, you may be asked by your supervisor to present on the cost of a specific project. Imagine you are a project manager and you are supervising a charity event for your company. You know that the venue will cost $1500 to rent for an evening. You also know that it will cost $25 dollars per person. Create an equation in slope-intercept form (y=mx+b) to represent this scenario, where m is the slope (change per person) and b is the y-intercept (starting amount). Find three solutions for this equation in the form of ordered pairs.

Question 1058560: My dad enjoyed jogging at night. He would have his little MP3 player with him listening to either R&B, jazz, or news while he did this nightly ritual. In a hypothetical situation, Dad had exactly 14 hours and 5 minutes of audio content on his device. The linear equation 6x+4y+125=845 can help determine how many jazz songs, x, and how many R&B songs, y, Dad had on his mp3 player. Based on this equation, how many R&B songs and jazz songs combined were on my dad's device if the number of songs for each genre was the same?
