The Members of a cooking club are making cakes, which they will sell at a street fair for 25$ each. It cost 19$ for a booth at the fair, and the ingredients for each cake cost $6. At some point, the club members will sell enough cakes so that their sales cover their costs. How much will the sales and costs be? How many cakes will they have sold? PLZ ANSWER AS SOON AS POSSIBLE< THANK YOU

it takes one cake to cover the costs of the cake and the booth evening out the money but to make a profit they would need to make at least 2 cakes making a profit of 19 dollars do to the fact that the booth is a one time pay so at least 2 cakes
