The dishwasher's initial price was $450. During the 15% off promotion, the dishwasher's price will be lowered by: 15% of $450 = 0.15 x $450 = $67.50 So, the dishwasher's retail price will be: $450 - $67.50 = $382.50 As an employee, the person saves an additional 20% on the lowest price, which is $382.50. We may compute the extra discount as follows: 20% of $382.50 = 0.20 x $382.50 = $76.50 So the ultimate cost that the employee will pay for the dishwasher is: $382.50 - $76.50 = $306.00 As a result, the employee will pay $306.00 for the dishwasher.
Original price = x, 80/100 = 12590/X, 80X = 1259000, X = 15,737.50
The ratio of black and blue pens is 7 to 28, or 7:28. Dividing both sides by 7 yields 1:4.
This is an inverse ratio problem. 1/x = 1/a + 1/b, where an is Jenny's painting time, b is Mark's painting time, and x is the combined painting time of Jenny and Mark. So, 1/x = 1/4 + 1/6 We use the smallest common multiple in the denominator, 24. 1/x = 6/24 + 4/24 1/x = 10/24 x = 24/10 x equals 2.4 hours. In other words, 2 hours plus 0.4 hours is 2 hours plus 0.4 times 60 minutes. = 2 hours, 24 minutes.
