could you please explain/show how to do these questions whilst using excel?

Suzy's sister, Sandy, wants to sell sandwiches from a truck she will name "Sandy's Wiches." She figures half her customers will order the $5 sandwich, half will order the $7 sandwich. Each sandwich will cost her $1 to make (there are slight differences in costs but not enough to worry about). Her truck, equipment, and supplies will cost $36,000 per year in fixed costs plus she want to make $2,000 per month profit for her own income. How many sanwiches per day will she need to sell to break even if she is willing to work 6 days a week?
