<span>(u + 7) + 13 = u + (7 + 13) The associative property of addition says that you can add numbers regardless of how they're grouped and get the same result. So let's look at the options and see what makes sense. (u + 7) + 13 = u + (7 + 13) * This is showing the associative property like the definition states. So this is the correct choice. 21 + 2y = 2y + 21 * This is a demonstration of the commutative property of addition. So it's the wrong choice for this question. 3â‹…(5â‹…x)=(3â‹…5)â‹…x * This is showing the associative property of multiplication. So it's the wrong choice for this question. If m + 3 = 18, then 18 = m + 3. * This is a demonstration of the symmetric property of equality. So for this question, it's the wrong choice.</span>

A laptop is on sale for 45% off the regular price. If the sale price is $299.75, what was the original price?
Wewaii [24]

The original price of the laptop is calculated as $545

<h3>How to find the original Price?</h3>

We are given;

Sales Price of Laptop = $299.75

Now, the laptop is on sale for 45% off regular price.

If original price is x, then we can express that;

(100% - 45%) * x = 299.75

Thus;

55%x = 299.75

0.55x = 299.75

x = 299.75/0.55

x = $545

Thus, the original price of the laptop is calculated as $545
