Answer:you need to sell 25 muffin baskets before you will begin to make profit
Explanation:
Let x represent the number of muffin baskets that you fill.
Each empty basket will cost $2.50 to purchase and you will fill it with muffins that you have baked.
You have spent $75 on muffin mix ingredients.
Total cost of x baskets filled with baked muffins is
2.5x + 75
If you sell your muffin baskets for $7.50 each, then total amount received for x muffin baskets would be 7.5x
At the point where you begin to make profit,
2.5x + 75 = 7.5x
7.5x - 2.5x = 75
5x = 75
x = 15
