To earn some money, John is thinking of staring up a "Back-Yard BBQ" stand at his university campus this summer. The basic "BBQ" equipment will cost $3390

3390, and the variable cost (VC) for each "BBQ Meal" is estimated to be $6.30

6.30. He thinks he will be able to sell each "BBQ Meal" for $8.75

(a) What is the break-even quantity of "BBQ Meals" for John's "Back-Yard BBQ" stand?
(b) If John's goal for profit is $2500

2500 for his fall semester tuition, how many "BBQ Meals" would he need to sell in the summer to reach his goal?
