How to find the total weekly earnings?
The waitress has a fixed salary of $275, and then we need to find the 3% of the dinners that she served.
Remember that the 3% of a number N is given by:
(3%/100%)*N = 0.03*N
The 3% of the total worth of the dinners she served is:
0.03*($4,800.00) = $144
If we add that to the fixed salary, we get:
$275 + $144 = $419.
We can conclude that her total weekly earnings are $419.
