Answer :
- Add the amount of garbage Ralph took (72 pounds) and the amount Kyle took (66 pounds).
- Perform the addition: $72 + 66 = 138$.
- The total amount of garbage they got rid of is 138 pounds.
- The final answer is $\boxed{138}$.
### Explanation
1. Understanding the problem
We need to find the total weight of garbage that Ralph and Kyle got rid of. Ralph took 72 pounds of garbage, and Kyle took 66 pounds of garbage. To find the total weight, we need to add the weight of Ralph's garbage to the weight of Kyle's garbage.
2. Setting up the equation
The total weight of garbage is calculated by adding the individual weights:$$Total = Ralph's \ garbage + Kyle's \ garbage$$$$Total = 72 + 66$$
3. Calculating the total weight
Adding the two numbers, we get:$$72 + 66 = 138$$So, the total weight of garbage is 138 pounds.
4. Finding the answer
Comparing our result with the given options, we see that option A, $72+66=138$, matches our calculation. Therefore, the correct answer is 138 pounds.
### Examples
Imagine you're helping clean up a park with your friend. You collect 72 pounds of trash, and your friend collects 66 pounds. Adding these amounts helps determine the total trash collected, showing the combined effort in keeping the park clean. This simple addition is useful in many real-life situations, such as calculating the total cost of items you buy or the total distance you travel on a trip.
