Answer:
Joel must sell minimum 41 cones in order to make a profit.
Explanation:
We are given the following in the question:
Selling price of 1 cone = $1.40
Rent on equipment = $36
Cost of ingredients on each cone = $0.52
Let x be the amount of cones.
Then, in order to have a profit. the total selling price should be greater than the cost price.
Thus, we can write the equation:

Thus, 41 is the minimum number of cones that Joel must sell in order to make a profit.
