Hi, I need help to solve these 2 questions. Thank you.
1. A bookshop was selling some calendars. The bookshop could make a profit of $18 from the sale of each calendar. After selling some calendars, the selling price of the remaining calendars was reduced by $10 each. The number of remaining calendars was 2/3 of the number of calendars sold at the original price. The bookshop made a total profit of $2870 after selling all the calendars. How many calendars were sold altogether?
2. Allan had 60 more stamps than Becky. They each gave some of their stamps to their friends. The number of stamps Becky gave away was 2/5 of the number of stamps Allan had at first, the number of stamps Allan gave away was 2/3 of the number of stamps Becky had at first. Both had an equal number of stamps left. How many stamps did Allan have at first?
