Answer:
$100, $140
Explanation:
[tex]\sf \rightarrow \dfrac{1}{2} |x-120| = 10[/tex]
[tex]\sf \rightarrow |x-120| = 2(10)[/tex]
[tex]\sf \rightarrow |x-120| = 20[/tex]
[tex]\sf \rightarrow x-120 = \pm 20[/tex]
[tex]\sf \rightarrow x-120 = 20 \quad or \quad x - 120 = -20[/tex]
[tex]\sf \rightarrow x= 20+120 \quad or \quad x = -20+120[/tex]
[tex]\sf \rightarrow x= 140\quad or \quad x = 100[/tex]
Hence, the least amount is $100 and greatest amount is $140.
