Answer:
The salary decreased by 45%
Step-by-step explanation:
Given,
The previous salary of Trent is $143,020
The current salary of Trent is $78,661
The decrease in salary is $143,020 - $78,661 = $64,359
When he used to get $143,020, the decrease in salary is = $64,359
When he used to get $1, the decrease in salary is = $64,359/$143,020
When he used to get $100, the decrease in salary is = $64,359*100/$143,020
= $64,35900/$143,020
= 45%
