Understand Problem: Understand the problem and identify what is given and what needs to be found. We are given that Joseph's Books sold 741 bookmarks this year, which is 90% more than last year. We need to find the number of bookmarks sold last year.Let x be Number: Let the number of bookmarks sold last year be x. According to the problem, the number of bookmarks sold this year is 90% more than last year. This means that this year's sales are 100% of last year's sales plus an additional 90% of last year's sales.Translate into Equation: Translate the information into an equation. The equation to represent the situation is: 741 = x + 0.90xCombine Like Terms: Combine like terms to simplify the equation. 741 = 1x + 0.90x 741 = 1.90xSolve for x: Solve for x by dividing both sides of the equation by 1.90. x = 741 / 1.90Perform Division: Perform the division to find the value of x. x = 390Verify Solution: Verify that the solution makes sense in the context of the problem. If Joseph's Books sold 390 bookmarks last year, then 90% more would be 390 * 0.90 = 351 bookmarks more. Adding the additional bookmarks to last year's sales gives us 390 + 351 = 741 bookmarks, which matches the number given for this year's sales.
