Juan Ramirez sells suits in a major department store on weekends. He earns a commission of 5 percent on the first ten suits, and if he sells more than ten, he earns an additional 3 percent on the additional suits. Last weekend Juan sold thirteen $250 suits. $185.00 was his commission. Solution: 10 (250 *.05) + 3 (250 *.08) = $185.00 commission.

John and Mary Billings own a condominium with an assessed value of $110,000. If the tax rate is 25 mills per $1.00 of assessed valuation, the tax they have to pay is $2,750. 110,000 X .025 = 2,750.

Expenditure = $150 on food, $244 on a car payment, $300 on rent= 150+300 +244 =$694 , savings = $50, income he spend on other things = $1,240 - $694 - $50 = $496 ,percentage = 496 /1240 *100 =40%.

Starting balance: $785.63
check for groceries: - $57.00
check for a car payment: - $125.00
deposit: + $57.25 So: $785.63 - $57.00 - $125.00 + $57.25 = $660.88 Mary's current balance.
