Therefore the numerator must have a factor of 7 in it so that the simplified fraction has a denominataor that has a prime factorization of only 2ʹs and 5ʹs. Therefore x can be any multiple of 7 that is less than 3500. 28) 100 grid represents 900 l column represents 90 1 small square represents 9 Therefore 225 is 2 columns and 5 squares 2(90) + 5(9) =180 + 45 2 columns and 5 small square is 25% of the grid. Thus the answer is 25%. 39 50 4 30) 0.428571 31) 14 stops 32) 2 3 33) 4 34) \$20,720 35) \$613 36) 32% 37) 60% 38) \$7200 39) Answers will vary. Possible answer: The item has not been restored to its original price. Its price is now lower than the original price. The amount of the increase was less than the amount of the discount because 20% of the sale price...
