Kris has two choices for a part-time job after school. Kris could make 10 per hour entering data for a local company, but none of his friends work there. The second job offer pays 8 per hour at a local restaurant, and many of his friends work there. If Kris works 20 hours per week, what would be the weekly opportunity cost of accepting the job at the restaurant? 120 40 20 160

## Step1: Calculate Earnings from Data Entry Job<br />### Kris earns \$10 per hour at the data entry job. For 20 hours per week, his total earnings would be \( 10 \times 20 = 200 \) dollars.<br />## Step2: Calculate Earnings from Restaurant Job<br />### Kris earns \$8 per hour at the restaurant job. For 20 hours per week, his total earnings would be \( 8 \times 20 = 160 \) dollars.<br />## Step3: Determine Opportunity Cost<br />### The opportunity cost is the difference in earnings between the two jobs. Thus, it is \( 200 - 160 = 40 \) dollars.<br /><br />#
