Question 893781: a welder earns $20 per hour for the first 40 hours she works in a week and $30 per hour or each hour over 40 hours. Write a peicewise function f(x) that can be used t to determine the welders earnings when she works for x hours in a week

Suppose she works X hours in a week.
According to question, if x < 40
$20 per hour for the first 40 hours
hence Total earnings F(x) = 20 X
If X>40
$20 per hour for the first 40 hours
Hence earnings for the first 40 hours= 20*40 = $800
Total earnings F(x)= 800 + 30(X-40)
