Janet makes $20 per hour at work. She works 52 hours per week. Anything over 40 hours per week is considered overtime and is paid at 1.5 times the normal rate. She wants to purchase a $4640 car. How many weeks does she need to work to purchase the car?
Let's think: Each week she makes $20 * 40 = $800 from her normal hours. For overtime she makes $20 * 1.5 = $30 per hour. Each week she works 52 - 40 = 12 overtime hours per week. She makes a total of 12 * $30 = $360 from overtime every week. This means she makes a total of $800 + $360 = $1160 per week. To reach $4640 she would need to work $4640 / $1160 = 4 weeks.. The answer is: 4.

Trip wanted to watch the new action movie in theaters. An evening ticket cost $10 and a large popcorn & drink combo would cost him an additional $10. He noticed on their website, they had a special offer. From 12 noon to 3 pm, save 20% off tickets and 50% off any food combos. How much money could Trip save by going to the earlier movie?
Let's think: An evening movie is $10 and the food combo would be $10 so 10 + 10 = $20. If he goes to an earlier movie, it's 20% off the normal ticket price of $10 so 10 * .20 = $2. If he goes to an earlier movie, it's 50% off the normal food price of $10 so 10 * .50 = $5. If he saves $2 for the ticket and $5 on food, then 2 + 5 = $7 saved.. The answer is: 7.

There are 60 ridges on a vinyl record. Jerry has 4 cases, each with 3 shelves that can hold 20 records each. If his shelves are 60% full, how many ridges are there on all his records?
Let's think: First find the total number of records that can fit on all the shelves: 4 cases * 3 shelves / case * 20 records / shelf = 240 records. Then multiply that number by 60% to find the number of records actually on the shelves: 240 records * 60% = 144 records. Then multiply that number by 60 to find the number of ridges on all the records: 144 records * 60 ridges / record = 8640 ridges.. The answer is: 8640.

Johnny makes his signature crab dish 40 times a day. It uses 1.5 pounds of crab meat. Crab meat sells for $8 per pound. How much does he spend in a week if he is closed 3 days a week?
Let's think:
He uses 40 * 1.5 = 60 pounds of crab meat per day. That cost 60 * 8 = $480 per day. He is open 7 - 3 = 4 days a week. So he spends 480 * 4 = $1920 a week.. The answer is: 1920.
