Answer is Php 184.15
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 :
[tex]100.00 + 55.65 + 28.50[/tex]
We will start adding the digits from right to left
[tex]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[/tex]
Now , Add all the answers :
[tex]100 + 70 + 13 + 1.1 + 0.05 = 184.15[/tex]
Hence, she earned Php 184.15 on the three days.
