Question

. The total cost of a gadget including material, labor, process, packaging and shipping comes to $3.29 perunit. How many gadgets must be sold at $4.99 in order to see a profit of $5000?

Answer 1

2,942.

The profit made on an individual item is the price minus the cost. 4.99 - 3.29 = 1.7.

For a profit of $5000, you have to sell x number of items. If the profit on individual items is $1.70, the equation is 5000 / 1.7 = x.

When this is solved, x is about 2,941.18. We round this up to 2,942 because you are unlikely to sell a fractional item.
