Step 1 :First, calculate the cost price per dozen after the discounts: \(\$7.00 \times (1 - 0.20) \times (1 - 0.19) = \$7.00 \times 0.80 \times 0.81 = \$4.536\)
Step 2 :Next, calculate the overhead cost: \(0.48 \times \$4.536 = \$2.17728\)
Step 3 :Now, calculate the required profit: \(0.25 \times \$4.536 = \$1.134\)
Step 4 :Add the cost price, overhead cost, and required profit to find the selling price per dozen: \(\$4.536 + \$2.17728 + \$1.134 = \$7.84728\)
Step 5 :Round the selling price to the nearest cent: \(\boxed{\$7.85}\)
