Answer:
Explanation:
A+K+L=159
A-K=11
2K=L
Plug in 2K instead of L in the equation: A+K+L=159
A+3K=159
Plug in K+11 instead of A in the equation: A+3K=159
4K+11=159
4K=148
Kevin=$37
Pluge in 37 instead of K in the equation: A-K=11
A-37=11
Austin=$48
Plug in 48 instead of A and 37 instead of K in the equation: A+K+L=159
48+37+L=159
L=74
