A jewelry box has 10 necklaces and 15 earrings. Jessy goes to the jewelry stores and buys 10 more necklaces and 2/3 as many earrings as before. After returning home, her mother gives her 1/5 times more earrings than the number she purchased at the store. Calculate the total number of jewelry pieces Jessy has in her box if she puts all of them together. Give me reasons, before answering the question
The total number of jewelry Jessy had before going to the store is 10 necklaces + 15 earrings = 25. At the store, Jessy bought 2 / 3 * 15 = 10 earrings. When she got back from the store, Jessy received 1 / 5 * 10 = 2 more earrings than the ones she bought at the store from her mother. The total number of earrings Jessy received from her mother is 2 + 10 = 12 earrings. The total number of earrings Jesy has after being given 12 more from her mother is 10 + 12 = 22 earrings outside the jewelry box. When Jessy puts all the jewelry in the box, the total number becomes 22 new earrings + 10 new necklaces + 25(the total number of jewelry she had before) = 57. So the final answer is 57.
