so 250% of 28,000 is 2.50 times 28,000 which is 70,000.
28,000 is increased by 70,000 to 98,000
250% x 28,000 + 28,000 (we add 28000 because it's an increase so we have to add it to the original amount).
250% x 28000 =
2.5 x 28000 = 70,000
Now add it back to the original 28,000
70,000 + 28,000 = 98,000

5x+20=3x+23
5x-3x=23-20
2x=3
x=3/2
5X + 20 = 3X + 23
5X - 3X = 23 - 20
2X = 3
X = 3/2
X = 1 1/2

discount: 15% off
sale price: ?
There are two ways you can solve this problem:
Here's the longer way (by one step):
65 * .15 (15% in decimal form) = 9.75
65 - 9.75 = 55.25
sale price = $55.25
Here's the method that's one step shorter:
65 * .85 (100-15 ~ because it's 15%[15/100] off) = 55.25
sale price = $55.25
Either way works for solving discounts/sales.

*To solve an inequality, it's the same as if you were solving an equation: Isolate the desired variable to one side to solve.
Firstly, subtract 15 on both sides:
Next, you are going to divide both sides by -30. Since you are dividing by a negative, you are going to flip the inequality symbol. Your final answer will be:
