[Question]Brendan works online and is paid every week. Once he gets the money, he recharges his debit card with half of his pay. In June, he earned $5000 and bought himself a used car worth $1500. What is his total amount of remaining money at the end of the month?
[Answer]The total amount of money used to charge the debit card is 1 / 2 * $5000 = $2500. When he buys the used car, he still has $2500 - $1500 = $1000 left. The answer is 1000.
Q: Rene has three times as many dolls as her sister, while her sister has two more dolls than their grandmother. If their grandmother has 50 dolls, how many dolls do they have altogether?
A: If the grandmother has 50 dolls, Rene's sister, who has 2 more dolls than their grandmother, has 50 + 2 = 52 dolls. Together, Rene's sister and the grandmother have 52 + 50 = 102 dolls. Since Rene has three times as many dolls as her sister, she has 52 * 3 = 156 dolls. Altogether, they have 156 + 102 = 258 dolls. The answer is 258.
Question: Tatuya, Ivanna, and Dorothy took a quiz together. Tatuya scored twice as much as Ivanna, and Ivanna scored 3/5 times as many marks as Dorothy. If Dorothy scored 90 marks, calculate the average marks scored by the three.
Answer: Since Dorothy scored 90 marks, and Ivanna scored 3 / 5 times as many marks, Ivanna scored 3 / 5 * 90 = 54 marks. Together, Dorothy and Ivanna scored a total of 54 + 90 = 144 marks. If Tayuta scored twice as many marks as Ivanna, she scored 2 * 54 = 108 marks. The total marks the three scored altogether is 108 + 144 = 252 marks. The average marks for the three are 252 / 3 = 84 marks. The answer is 84.
[Question]Sally, Sam, and Steve went to play with their marbles. In the beginning, Sam has twice as many marbles as Steve while Sally has 5 less than Sam. After Sam has given Sally and Steve 3 marbles each, Sam has 8 marbles left. How many marbles does Steve have now?
[Answer]Sam has 8 marbles left after giving 3 marbles / person x 2 people = 6 marbles to Sally and Steve. Hence, Sam had 8 marbles + 6 marbles = 14 marbles in the beginning. Sam had twice as many marbles as Steve, therefore Steve has 14 marbles / 2 = 7 marbles in the beginning. So now, Steve has a total of 7 marbles + 3 marbles = 10 marbles after Sam gave him 3 marbles. The answer is 10.
[Question]Marj has two $20 bills, three $5 bills, and $4.50 in loose coins in her wallet. If she buys a cake that costs $17.50, how much money will be left in her wallet?
[Answer]
Two $20 bills amount to $20 x 2 = $40. Three $5 bills amount to $5 x 3 = $15. So, Marj has $40 + $15 + $4.50 = $59.50 in her wallet. If she buys a cake, she will be left with $59.50 - $17.50 = $42. The answer is 42.
