Q: Christi saw twice as many black bears as white bears and 40 more brown bears than black bears in a national park. If the number of black bears in the park is 60, calculate the population of bears in the park.
A: If there are 60 black bears in the park and 40 more brown bears than black bears, there are 60 + 40 = 100 brown bears. The number of black and brown bears in the park is 100 + 60 = 160. Twice the number of black bears as white bears means 60 / 2 = 30 white bears. The population of bears in the national park is 30 + 160 = 190. The answer is 190.
Question: It was reported that 2000 cases of Coronavirus had been confirmed in the state of New York in May 2020. There was half the number of cases in California, which had 400 more cases than the state of Texas. What's the total number of cases that had been confirmed in all of these states?
Answer: If California had half the number of Coronavirus cases in New York, then the number of cases was 2000 / 2 = 1000 cases. California had 400 more cases than the state of Texas, thus Texas had 1000 - 400 = 600 cases. The total number of Coronavirus cases in all of the three states is 600 + 1000 + 2000 = 3600 cases. The answer is 3600.
[Question]Paul needed to buy some new clothes for work. He had a 10% off coupon that he could use on his entire purchase after any other discounts. Paul bought 4 dress shirts at $15.00 apiece, 2 pairs of pants that each cost $40.00. He found a suit for $150.00 and 2 sweaters for $30.00 each. When he got to the register, the clerk told him that the store was offering 20% off of everything in the store. After the discounts and the coupon, how much did Paul spend on his new clothes?
[Answer]4 dress shirts cost $15.00 each so 4 * 15 = $60.00. 2 pants at $40.00 cost 2 * 40 = $80.00. 2 sweaters at $30.00 cost 2 * 30 = $60.00. Add the suit at $150 and the other items the total was 150 + 60 + 80 + 60 = $350. The store has having a 20% off sale so .20 * 350 = $70.00 discount. His new total would be 350 - 70 = $280.00. Then add his 10% discount, .10 * 280 = $28.00 additional off. His final total came out to 280 - 28 = $252.00. The answer is 252.
Q: A couple opened a savings account. The husband gives $335 every week while the wife gives $225 every week. After 6 months of saving (assume 4 weeks in each month), they decided to divide half of the couple's savings into their four children's savings accounts. How much does each child receive?
A: The husband saves $335 x 4 = $1340 a month. The wife saves $225 x4 = $900 a month. Together, they save $1340 + $900 = $2240 in a month. In 6 months, their total savings is $2240 x 6 = $13440. Half of the couple's savings is 13440 / 2 = $6720. Therefore, each child will receive 6720 / 4 = $1680. The answer is 1680.
Question: The community leader of a certain town organized a cleaning day event where community members were to be involved in collecting trash inside the town. Out of 2000 community members involved in the cleaning process, 30% were adult men. If there were twice as many adult women as adult men in the event, and the rest were children, calculate the total number of children involved in the cleaning event.
Answer: If the number of adult men involved in the cleaning process was 30% of the community members, there were 30 / 100 * 2000 = 600 adult men at the event. There were also twice as many adult women as adult men in the event, a total of 2 * 600 = 1200 women. The total number of adults in the event was 1200 + 600 = 1800. If the rest of the people at the cleaning event were children, there were 2000 - 1800 = 200 children at the event. The answer is 200.
Q: A small, old, wooden bridge can hold up to 100 kilograms at once. Mike, Megan, and Kelly are three children who decided to cross the bridge at the same time. Kelly weighs 34 kilograms, which is 15% less than Megan. Mike weighs 5 kilograms more than Megan. How much too much do the three children weigh together to cross the bridge?
A:
If Kelly weighs 15% less than Megan, this means Kelly's weight is 100 - 15 = 85% of Megan's weight. 85% is 0.85, so Megan weighs 34 / 0.85 = 40 kilograms. Mike weighs 5 kilograms more than Megan, so he weighs 40 + 5 = 45 kilograms. In total all three kids weigh 34 + 40 + 45 = 119 kilograms. That means to cross the bridge safely, they weigh 119 - 100 = 19 kilograms too much. The answer is 19.
