Joel sells ice cream cones at the county fair. He has to rent the equipment for $36 and spend $0.52 on ingredients for each cone. What is the minimum number of ice cream cones Joel must sell at $1.40 each in order to make a profit?

Joel must sell minimum 41 cones in order to make a profit.

Step-by-step 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.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
