Well, we would first have to add the amount of cookies he gives to ONE person, and then multiply that by 19 since he has 19 employees. Since he gave 6 chocolate chip and 2 peanut butter cookies, we'd have to add 6 + 2 which equals 8. Now that we know Frank gave 8 cookies per person, we have to calculate how many cookies he gave to ALL his employees, by multiplying 8 by the total amount of employees, (19), so now we'd do 8 times 19 = 152, so that means he gave 152 cookies to all his employees. c:
