let
x = the number of optional features that cost $23.99
y = the number of optional features that cost $120.84
Melissa bought a new car with 12 optional features to the car
x + y = 12
she paid $675.28 for all the optional feature
23.99x + 120.84y = 675.28
by solving the system of equations
x + y = 12
23.99x + 120.84y = 675.28
we find
x = 8 features
y = 4 features
