Answer:
$42,000
Step-by-step explanation:
Let L be the lowest possible salary;
the maximum salary would be (L x 20%) + L = 1.2L
If we want to determine the minimum value for L, we need to assume that everyone else earns the maximum salary: 20 employees earn 1.2L each
L + 20(1.2L) = 1050000
L + 24L = 1050000
25L = 1050000
L = 42000
