Q: Out of 480 employees, 10% got a salary increase while 20% got a travel allowance increase. How many employees did not get any increase?
A: 480 x 10 / 100 = 48 employees got a salary increase. 480 x 20 / 100 = 96 employees got a travel allowance increase. So a total of 48 + 96 = 144 employees got an increase. Therefore, 480 - 144 = 336 employees did not get any increase. The answer is 336.
Question: Sally sold 20 cups of lemonade last week. She sold 30% more lemonade this week. How many cups of lemonade did she sell in total for both weeks?
Answer: If Sally sold 30% more lemonade this week, she sold 20 * 30 / 100 = 6 more cups this week. This week, Sally sold 20 + 6 = 26 cups of lemonade. In total for both weeks, Sally sold 20 + 26 = 46 cups of lemonade. The answer is 46.
[Question]The mayor commissioned two artists to paint 50 murals around the city. Once the work was completed, Celina was paid $1,000 more than 4 times the amount Diego got. If the mayor paid the two a total of $50,000, how much did Diego get?
[Answer]Let d be Diego's payment. Both artists were paid (1000 + 4 * d ) + d = 50000 dollars. This means that 5d = (50000 - 1000) dollars. Therefore Diego was paid d = 49000 / 5 = 9800 dollars. The answer is 9800.
Q: Ralph is a member of the cross-country relay team. There are four other members on the team who run 3 km to complete their part of the race. Ralph runs twice as much as any member on his team to complete his part of the race. How long is the race?
A: 4 team members each run 3 km, so 4 x 3 = 12 km. Ralph runs twice as much as any team member and since team members each run 3 km, Ralph runs 2 x 3 km = 6 km. The length of the race is 6 km run by Ralph + 12 km run by the rest of the team = 18 km. The answer is 18.
