Answer:
w = 120 + 5*(h-30)
Step-by-step explanation:
Part A;
We are informed that Andrew is paid $4 per hour for the first 30 hours he works each week and makes $5 per hour for each hour he works over 30 hours per week. This implies that the $4 per hour for the first 30 hours is fixed while the $5 per hour overtime depends on the number of extra hours worked.
If we let w denote the wage and h denote the hours worked per week, then;
$4 per hour for the first 30 hours; 4*30 = 120
The number of extra hours worked would be; h-30
w = 120 + 5*(h-30)
This is the function that gives Andrew’s total wages when he works more than 30 hours each week.
