To calculate the profit Jimmy will make, we need to determine the cost of the carpet and the revenue he generates from selling it.
The cost of the carpet is given as $0.12 per square foot, and he sells 120 square feet. Therefore, the cost of the carpet would be 0.12 * 120 = $14.40.
The selling price is $0.15 per square foot, and he sells 120 square feet. Thus, the revenue generated from selling the carpet would be 0.15 * 120 = $18.00.
To find the profit, we subtract the cost from the revenue: $18.00 - $14.40 = $3.60.
Therefore, Jimmy will make a profit of $3.60.
