Answer this question:Beth has 72 marbles of three colors. Each color has the same amount of marbles. If Beth loses 5 red, twice as many blue, and three times as many yellow ones than red ones, how many marbles does she have left?
Beth has 72 / 3 = 24 marbles of each color. Beth has 24 - 5 = 19 red ones left. Beth lost 5 * 2 = 10 blue ones. Beth has 24 - 10 = 14 blue ones left. Beth lost 5 * 3 = 15 yellow ones. Beth has 24 - 15 = 9 yellow ones left. She has a total of 19 + 14 + 9 = 42 marbles left.
The answer is 42.

Answer this question:A car traveled 360 miles in 4 hours and 30 minutes. What was its speed in miles per hour?
There are 60 minutes in one hour, so the car traveled 360 miles in 4 hours + 30 minutes / 60 minutes / hour = 4.5 hours. In one hour, the car travels 360 miles / 4.5 hours = 80 miles / hour.
The answer is 80.

Answer this question:Cadence has worked for her new company five months longer than she worked for her old company. If she worked at her old company for 3 years earning $5000 per month, and she's now earning 20% more in the new company, calculate the total amount of money she's earned in both companies in the period she's worked for them?
In her old company, if she worked for three years, the total number of months she was paid for is 3 years * 12, which is the number of months in a year = 36 months. If each month she was paid $5000, her total earnings in the old company were $5000 * 36 = $180000. In her new company, she is paid 20% more, which is 20 / 100 * $5000 = $1000 per month more than what she was paid at the old company. In total, she earns $5000 + $1000 = $6000 per month in her new company. Since she's worked five months more in the new company than the old company, she has worked for 36 + 5 = 41 months in the new company. The total amount she's earned in the new company is $6000 * 41 = $246000. The combined total for both companies is $246000 + $180000 = $426000.
The answer is 426000.
