Harold makes $2500.00 a month from his job. His rent is $700.00, his car payment is $300.00, his utilities cost 1/2 the amount of his car payment and he spends $50.00 on groceries. He wants to put half of the remaining money into a retirement account. How much money will that leave him?
Let's think: His utilities cost 1 / 2 the amount of his $250.00 car payment so his utilities cost 250 / 2 = $125.00. All total, his bills cost him 775 + 250 + 125 + 50 = $1,200. He makes $2500 a month and his bills cost $1200 a month so that leaves him with 2500 - 1200 = $1300.00. He wants to put half of $1300 into a retirement account so he will invest 1300 / 2 = $650 into his retirement account. He had 1300 and puts $650 into his retirement account so that leaves him with 1300 - 650 = $650 remaining.. The answer is: 650.

Keesha wants to get her hair and nails done for prom. Hair updos cost $50 and manicures cost $30. How much will these two services cost her with a 20% tip for each beautician?
Let's think: Tip for the hair stylist will be $50 x 20% = $10. Tip for the manicurist will be $30 x 20% = $6. Total tips will be $10 + $6 = $16. Total for hair and nails is $50 + $30 = $80. Total for the two services plus tip is $80 + $16 = $96.. The answer is: 96.

Antonia is trying to improve her health by buying supplements. She has a 7-day pill box she wants to fill. She buys 5 different supplements. 3 of the bottles have 120 pills in them each. 2 of the bottles have 30 pills each. After Antonia has filled her pillbox with one pill of each supplement for 2 weeks, how many pills total does she have left from all 5 bottles?
Let's think: Antonia buys 5 different supplements where 3 bottles have 120 pills per bottle, so she has 120 pills x 3 bottles = 360 pills. 2 of the bottles Antonia buys have 30 pills each x 2 bottles = 60 pills. She has purchased 360 pills + 60 pills = 420 pills total in the 5 bottles. Antonia has filled her 7 - day pill box for 2 weeks, so 7 days x 2 weeks = 14 days. On each of the 14 days she fills it with 5 pills, so after 14 days she has used 14 x 5 = 70 pills. Since Antonia had 420 total pills in all 5 bottles and then she fills her pillbox with 70 pills, she has 420 - 70 = 350 pills. Antonia will have 350 pills left after 2 weeks.. The answer is: 350.

An auto shop buys tires to replace all the tires on every customer's car. They buy the tires as soon as cars are brought into the shop. There are four cars in the shop already, and another six customers come into the shop throughout the week. Some of the customers decide they don't want any of the tires changing, and two customers decide they only want half the tires changing. They had no tires in stock at the start of the week. If the shop has 20 tires left at the end of the week, how many customers decided they did not want their tires changing?
Let's think:
A total of 4 + 6 = 10 cars are in the shop throughout the week. This means the shop buys 10 cars * 4 tires = 40 tires. For each of the customers that only want half the tires changing, there are 4 tires * 0.5 = 2 tires left over. Two of the customers only want half the tires changing, so there are 2 tires * 2 cars = 4 tires left over from these customers. Out of the remaining tires, there are 20 4 = 16 tires left from customers who don't want their tires changing. So in total, there were 16 tires / 4 tires per customer = 4 customers who did not want their tires changing.. The answer is: 4.
