Question

Beverly sells donuts at the local bakery. Donuts cost $.50 each unless customers buy a dozen or more. When customers buy at least a dozen they cost $.40 each. Beverly earns a commission based on her sales performance. Because the bakery makes so much money on beverages, she earns 10% commission (based on the total sale) when a customer buys a drink. She also earns commission on her sales. She earns 2% on each sale that totals more than $10. She earns 1% commission on each sale that totals more than $5 (but less than $10). She does not earncommission on each sale that totals $5 or less (though she will earn the beverage commission). Complete the tablebelow to help Beverly calculate her commission based on the 50 customers she helped this morning.

Please show formulas, thanks!​

Answer 1

| # of Donuts | Cost of Donuts | Cost of Beverages | Total Sale | Commission |

|-------------|----------------|------------------|------------|------------|

| 1 | $0.50 | $2.00 | $2.50 | 0.00 |

| 6 | $3.00 | $2.00 | $5.00 | 0.00 |

| 12 | $4.80 | $2.00 | $6.80 | 0.68 |

| 18 | $7.20 | $2.00 | $9.20 | 0.92 |

| 24 | $9.60 | $2.00 | $11.60 | 1.16 |

| 30 | $12.00 | $2.00 | $14.00 | 1.40 |

| Total | | | $49.10 | $4.16 |

To calculate the cost of donuts, we can use the following formula:

Cost of donuts = (# of donuts x cost per donut)

To calculate the total sale, we can use the following formula:

Total sale = (cost of donuts + cost of beverages)

To calculate the commission, we can use the following formulas:

Commission for sales over $10 = (total sale x 2%)

Commission for sales over $5 (but less than $10) = (total sale x 1%)

Commission for beverages = (cost of beverages x 10%)

Total commission = (commission for sales over $10 + commission for sales over $5 + commission for beverages)
