If Ricky sells n shoes in a week, he earns $40n in commission. His salary is a constant $100 per week, so his total payout is $100 + $40n.

Profit = Income - Expenditures

Income = $6/floggle times 500 floggles = $3000

Expenditures = $1000 + $4/floggle times 500 floggles = $1000 + $2000 = $3000

Profit = 3000 - 3000 = 0

First determine total cost.

Caterer: Per person = $15 + $10 + $5 = $30 per person

Parking: Per person = $3 per person

Total per person = $33

$33 * 500 people = $16,500

Plus cost of renting venue + band = $2500 + $2000 = $4500

Total (net) cost =  $16,500 + $4500  = $21,000

Total (gross) cost = net cost + profit = $21,000 + $10,000 = $31,000

Cost per ticket = Gross cost / # of attendee = $31,000 / 500 = $62

Profit = Revenue – Expense

% Profit = $ Profit ÷ $ Total Revenue

% Profit = ($150,000 – $75,000) ÷ $150,000 = 50%

The answer is 23. 23*$4.50 = $103.50, which is more than what Nicki earned.

Total profit ($35) divided by total items (70) yields the answer of $0.50 profit per item.

Using $20 worth of supplies and selling the chairs for $50 each, the carpenter is originally making a profit of $30 per chair.

The new supplier would reduce costs by 25% or 1/4. One-fourth of $20 is $5, so the new supplier would be $5 less, or $15.

If the selling price is the same ($50), then the carpenter would now make a profit of $35 per chair, a change of $5.

To calculate percent increase, divide the actual change in profit by the original profit amount, and multiply the result by 100%:

(Actual Change ÷ Original Amount) * 100% = 5/30 * 100% = 500%/30 = 16.7%

Total Cost = Material Cost + Labor Cost + Profit

Labor Cost =  $40/hour * 20 hours = $800

Profit Margin of 50% = Cost x 0.50 = $1050 x 0.50 = $525

Total Cost = $250 + $800 + $525 = $1575

First we must find out what the price is for one teddy bear, manufactured by this company. Thus we divide 1750 by 200 and find that each bear costs $8.75. To find out the profit per bear, we divide 8.75 by 6.25 to arrive at 1.4. The bears are thus sold for 140% of what it costs to make them, giving a 40% profit.

A 10% sale means that the post-sale price of the item is now 90%, or 0.9 of the original cost of the item. We then apply 9% sales tax by multiplying the 0.9 by 109%, or 1.09. 0.9 * 1.09 = .981, so the total cost of the item is 98.1% of the original pre-sale sticker price.

For percentage problems that do not deal with a specific starting number, it is always helpful to plug in 100 for the starting number. Here, we would then have a post-sale price of 90 dollars, and if we calculate the sales tax for the 90-dollar item it would be 90 * 0.09 = $8.10. THis gives us a total cost of 90 + 8.10 = $98.10, or 98.1% of the original 100-dollar price.
