Q: Between them, Mark and Sarah have 24 traffic tickets. Mark has twice as many parking tickets as Sarah, and they each have an equal number of speeding tickets. If Sarah has 6 speeding tickets, how many parking tickets does Mark have?
A: First figure out how many total speeding tickets the two people got by adding the 6 speeding tickets Sarah got to the equal number (6) that Mark got: 6 + 6 = 12. Now subtract the combined number of speeding tickets from the total number of tickets to find the combined number of parking tickets: 24 - 12 = 12. Now express Mark's number of parking tickets in terms of the number of parking tickets Sarah got: m = 2s. We know that m + s = 12, so substitute in the value of m from the previous step to get 2s + s = 12. Combine like terms to get 3s = 12. Divide both sides of the equation to get s = 4. Now multiply the number of parking tickets Sarah got by 2 to find the number Mark got: 4 * 2 = 8. The answer is 8.
Question: A jewelry store is restocking its shelves. The necklace stand, which can hold 12 necklaces, currently holds 5 necklaces. The ring display, which can hold 30 rings, currently holds 18 rings. The bracelet display, which can hold 15 bracelets, currently holds 8 bracelets. The store’s supplier charges $4 per necklace, $10 per ring, and $5 per bracelet. How much, in dollars, will the store need to pay to fill the displays?
Answer:
The necklace stand needs another 12 – 5 = 7 necklaces. This will cost the store 7 * 4 = $28. The ring display needs another 30 – 18 = 12 rings. This will cost the store 12 * 10 = $120. The bracelet display needs another 15 – 8 = 7 bracelets. This will cost the store 7 * 5 = $35. In total, the store needs to pay 28 + 120 + 35 = $183. The answer is 183.
