can anyone please tell me how to do this

Hello there, this problem is just basic addition, here is what it would look like
[tex]52.31+25.90[/tex]
Solve it and we get 78.21
Amount earned on Saturday = $ 52.31
Amount earned on Sunday = $ 25.90
Total amount earned
= $ 52.31 + $ 25.90
= $ 78.21
Therefore, Tara earned $ 78.21 in total. Hope this helps.
Have a nice day.
