Answer: 42.5 hours
Step-by-step explanation:
Let the number of hours that the employee work be represented by x.
Since the employee spent 1.7 hours making work calls one week, which was 4% of the employee's total work hours for the week, this can be represented in an equation as:
4% × x = 1.7
4/100 × x = 1.7
0.04 × x = 1.7
0.04x = 1.7
x = 1.7 / 0.04
x = 42.5 hours
The employee worked for 42.5 hours
