Answer this question:Selena got a tip today that amounted to $99. She pampered herself by eating at a 5-star hotel. She indulged herself with 2 steak meals that cost $24 each plate. She also ordered 2 types of burgers which cost $3.5 each, and 3 cups of ice cream which cost $2 each. How much money will Selena be left with?
Selena was charged $24 x 2 = $48 for the steaks. She was charged $3.5 x 2 = $7 for the burgers. She was charged $2 x 3 = $6 for the cups of ice cream. She was charged $48 + $7 + $6 = $61 in total. Therefore, Selena was left with $99 - $61 = $38.
The answer is 38.

Answer this question:Maria has a pen and a pencil. She bought the pen for half the price of the pencil. The pencil cost her $8. How much did Maria pay for both the pen and the pencil?
The pen is half the price of the pencil, so it's 8 * 0.5 = $4. So both the pen and the pencil cost Maria 8 + 4 = $12.
The answer is 12.

Answer this question:Nancy's ex owes her child support. He's supposed to pay 30% of his income each year. For 3 years, he made $30,000/year, then he got a 20% raise for the next four years. If he's only ever paid $1,200, how much does he owe her?
First find how much money the ex made during the first 3 years by multiplying his annual earnings by the number of years: 3 years * $30,000 / year = $90,000 / . Then find how much his raise was by multiplying his salary by the percentage raise: $30,000 / year * 20% = $6,000 / year. Then add the raise to his original salary to find his new salary: $6,000 / year + $30,000 / year = $36,000 / year. Then find how much he made working at the new salary by multiplying it by the 4 years he worked: 4 years * $36,000 / year = $144,000. Add his earnings from the three years and the four years to find his total earnings: $144,000 + $90,000 = $234,000. Now multiply his total earnings by 30% to find how much he was supposed to pay: $234,000 * 30% = $70,200. Now subtract the amount he paid from this number to find how much he owes: $70,200 - $1,200 = $69,000.
The answer is 69000.
