Question

Turner just measured his dog and found out that it weighs 76 kilograms, which is 5% less than the last time Turner measured. How much did the dog weigh last time?​

Answer 1

To calculate the dog's original weight before losing 5% of its weight, we use the equation 'Original Weight x 0.95 = Current Weight'. The original weight was 80 kilograms when the current weight is 76 kilograms.

Step-by-step explanation:

The question involves determining the original weight of Turner's dog before a 5% weight decrease to the current weight of 76 kilograms. To find the original weight, we can set up a simple algebraic equation. Since 5% less weight is equal to 95% of the original weight, we have:

Original Weight x 0.95 = Current Weight

Let's call the original weight 'W'. Then,

W x 0.95 = 76 kg

To find 'W', we divide both sides of the equation by 0.95:

W = 76 kg / 0.95

W = 80 kg

So, Turner's dog weighed 80 kilograms the last time he measured it. As for the unit of measurement, when referring to the weight of a dog, using kilograms or pounds would be suitable. In cases where the dog weighs several hundred units, pounds would be an appropriate choice, but kilograms are also commonly used.
