Title: Re: Ronnie went to the bookstore and bought some books. He paid 1/6 of the total cost with cash, 2/4 ... Post by: andreathomas03 on Apr 17, 2023 Let's start by setting up an equation to represent the problem. Let x be the total cost of the books:
1/6x + 2/4x + 0.4(5)x = 20 To simplify this equation, we can first convert the fractions to a common denominator: 1/6x + 2/4x + 0.4(5)x = 20 = 1/6x + 3/6x + 2x = 20 = 11/6x = 20 Now we can solve for x: 11/6x = 20 x = 20/(11/6) x = $10.91 (rounded to two decimal places) Therefore, the books cost $10.91 in total. |
