Q: Marian's pending credit card balance is $126.00. She puts $60.00 worth of groceries on her card and half that amount in gas. She returned some bath towels for $45.00. What's the new balance on her credit card?
A: Her gas is half the price as her $60.00 groceries so that's 60 / 2 = $30.00 in gas. Her card has a balance of $126.00 and she added $60.00 in groceries and $30.00 in gas for a total of 126 + 60 + 30 = $216.00. Her balance is $216.00 and she returns $45.00 worth of merchandise for a new balance of 216 - 45 = $171.00. The answer is 171.
Question: Darius, Matt, and Marius are friends, who played table football. During all the games they played, Marius scored 3 points more than Darius, and Darius scored 5 points less than Matt. How many points did all three friends score together, if Darius scored 10 points?
Answer: If Darius scored 10 points, then Marius scored 10 + 3 = 13 points in total. Darius scored 5 points less than Matt, so Matt scored 10 + 5 = 15 points in total. So all three friends gathered 13 + 15 + 10 = 38 points. The answer is 38.
[Question]Kelly puts string cheeses in her kids lunches 5 days per week. Her oldest wants 2 every day and her youngest will only eat 1. The packages come with 30 string cheeses per pack. How many packages of string cheese will Kelly need to fill her kids lunches for 4 weeks?
[Answer]Her oldest wants 2 strings cheeses a day for 5 days so 2 * 5 = 10 string cheeses. Her youngest wants 1 string cheese a day for 5 days so 1 * 5 = 5 string cheeses. Together they want 10 + 5 = 15 string cheeses a week. Over 4 weeks, her kids will eat 15 string cheeses so 4 * 15 = 60 string cheeses. The bags have 30 per pack and she needs 60 so 60 / 30 = 2 packs of string cheese. The answer is 2.
Q: Harry decided to buy some balloons for his friend's birthday party. One balloon costs $0.5, and a pack of 10 balloons is cheaper and costs only $3. Finally, Harry wants to bring to the party exactly 14 balloons. How much did he need to pay for them?
A: To buy 14 balloons, Harry should buy one pack of 10, and 14 - 10 = 4 separate balloons. The price of 4 balloons is 4 * 0.5 = $2. In total, the pack and separate balloons would cost Harry in total 3 + 2 = $5. The answer is 5.

First find the number of students who went through breakups: 1 / 4 * 180 = 45 students. Then subtract that number from the total number: 180 students - 45 students = 135 students. Then divide that number by 3 to find the number of students who didn't show up to take the test: 135 students / 3 = 45 students. Then subtract the number of students who failed in each way from the total number to find the number who passed: 180 students - 45 students - 45 students - 20 students = 70 students. The answer is 70.
