Question

A worker needs to sell 12 sandwiches per hour to meet their quota. After 6 hours they have only sold 10 sandwiches per hour. How many sandwiches do they need to sell per hour in the remaining 2 hours to meet their quota?m

Answer 1

After 6 hours they have only sold 10 sandwiches per hour

6(10/hr)

60 + (x/hr)(2 hr) = (12/hr)(8hr)

60 + 2x = 96

2x = 36

x = 18

18 sandwiches per hour for two hours.
