Question: A hot dog stand sells 10 hot dogs every hour, each one selling for $2. How many hours does the stand need to run to make $200 in sales?
Answer: First, we find out how much in sales the stand makes each hour by multiplying the number of hot dogs sold by the sales price, finding that 2 * 10 = 20 dollars in sales each hour. Then we divide the sales goal for the day by the sales per hour, finding that the stand needs to be open for 200 / 20 = 10 hours to hit its sales goal. The answer is 10.
Q: A yearly book sale is held in school where students can sell their old books at a cheaper price. Two-fifths of Lovely's books can be sold for $2.50 each and the rest for $2 each. How much will Lovely earn if all 10 books were sold?
A:
Lovely will sell 10 x 2 / 5 = 4 books for $2.50 each. She will sell 10 - 4 = 6 books for $2 each. Her earnings for the 4 books at $2.50 will be $2.50 x 4 = $10. Her earnings for the 6 books for $2 each will be $2 x 6 = $12. Thus, Lovely's total earning if all 10 books are sold is $10 + $12 = $22. The answer is 22.
