Answer this question:Marie is planning to buy a new cash register for her bakery that costs $1040. Every day Marie sells 40 loaves of bread for $2 each and 6 cakes for $12 each. She has to pay $20 each day for rent and $2 each day for electricity. How many days' worth of profits will it take for Marie to pay for the cash register?
First figure out how much money Marie makes from selling bread each day by multiplying the number of loaves sold by the price per loaf: 40 loaves * $2 / loaf = $80. Next figure out how much money Marie makes from selling cakes each day by multiplying the number of cakes sold by the price per cake: 6 cakes * $12 / cake = $72. Now add the money from selling the bread to the money from selling the cakes to find Marie's total daily income: $80 + $72 = $152. Next subtract Marie's daily expenses from her daily income to find her daily profit: $152 - $20 - $2 = $130. Finally, divide the price of the cash register by Marie's daily profit to find how many days' profits she needs to pay for it: $1040 / $130 = 8.
The answer is 8.

Answer this question:Martha has 20 apples. She decided to split them among her friends. Jane got 5 apples from her, and James got 2 more than Jane. How many more apples would Martha need to give away to be left with only 4 of them?
Martha gave James 5 + 2 = 7 apples. So Martha was left with 20 - 5 - 7 = 8 apples. To be left with only 4 apples, Martha would need to give away 8 - 4 = 4 more apples.
The answer is 4.

Answer this question:To buy a book, you pay $20 for each of the first 5 books at the supermarket, and for each additional book you buy over $20, you receive a discount of $2. If Beatrice bought 20 books, how much did she pay at the supermarket?
For the first five books, the total cost is $20 * 5 = $100. For every additional book over $5, you pay $2 less, totaling to $20 - $2 = $18. Beatrice bought 20 books, so the number of books at which she received the $2 discount is 20 - 5 = 15 books. For the 15 books, Beatrice paid 15 * $18 = $270. In total, Beatrice paid $100 + $270 = $370 for the 20 books.
The answer is 370.

Answer this question:Mark spent 220 dollars to fix his car. It needed two parts that cost 20 dollars each, and labor cost .5 dollars a minute. How many hours did the mechanic work?
Labor cost is .5 * 60 = 30 dollars per hour. The cost for parts is 20 * 2 = $40. The total cost for labor is 220 - 40 = $180. He spent 180 / 30 = 6 hours on labor.
The answer is 6.
