Sorry, I remembered the rate at .28 when it was .33 per pound.
60 x .33 = $19.80 per hour
The IRS agents make similar assumptions in their audits and hold people at financial gunpoint.
I had an IRS agent press for criminal fraud for unrecorded gross receipts against several clients years ago by taking the pounds of flour purchased and multiplying by his recipe of pounds of flour per pizza based upon menu price to find unrecorded gross receipts.
I took seven cases to Federal Tax Count and walked in with two pizza boxes taped shut to show why they were wrong. They used a thin crust pizza recipe and my client made Sicilian pizzas. Their assumption cost my clients over $50,000 just to prove they were right.
