s, hours for Samuel
x, rate for Samuel
k, hours for Kathy
y, rate for Kathy

system%28x=2y%2Ck=3s%2Ck=36%2CsumOfWages%3E480%29

Sum of their wages:
x%2As%2By%2Ak
2y%2As%2By%2836%29
2y%2A%28k%2F3%29%2B36y
2y%2836%2F3%29%2B36y
2y%2A12%2B36y
24y%2B36y
60y---------the sum of their wages.

Referring to the system was necessary for some of those steps.

Now, highlight%2860y%3E480%29.
