<h3>
Explanation :-</h3>
Since Margie earned Php 100 on Saturday
Since Margie earned Php 55.65 on Sunday
Since Margie earned Php 28.50 on Monday
Then to get her earned on the 3 days, we will add the three amounts :
![100.00 + 55.65 + 28.50](https://tex.z-dn.net/?f=100.00%20%2B%2055.65%20%2B%2028.50)
We will start adding the digits from right to left
![0.00 + 0.05 + 0.00 = 0.05 \\ 0.5 + 0.6 + 0.0 = 1.1 \\ 8 + 5 + 0 = 13 \\ 20 + 50 + 0 = 70 \\ 0 + 0 = 100](https://tex.z-dn.net/?f=0.00%20%2B%200.05%20%2B%200.00%20%3D%200.05%20%5C%5C%200.5%20%2B%200.6%20%2B%200.0%20%3D%201.1%20%5C%5C%208%20%2B%205%20%2B%200%20%3D%2013%20%5C%5C%2020%20%2B%2050%20%2B%200%20%3D%2070%20%5C%5C%200%20%2B%200%20%3D%20100)
Now , Add all the answers :
![100 + 70 + 13 + 1.1 + 0.05 = 184.15](https://tex.z-dn.net/?f=100%20%2B%2070%20%2B%2013%20%2B%201.1%20%2B%200.05%20%3D%20184.15)
