We have been given that last year, the business had profit of $8000.
Further, we are given that, the profit for this year will be 5 times as great the profit of last year. So, in order to find profit of current year, we will have to consider 5 times of $8000.

1/4 cups = 1lb mince divide both by three
1/12 cups = 1/3lb hamburgers
1 1/3 cups = 12/12 cups + 4/12 cups
= 16/12 cups
=16 * 1/3lb hamburgers
- as 1/12 cups = 1/3lb burger, 16/12 cups = 16/3 lb burgers
Find the average value
12 hours + 10 hours = 22 hours
22 hours/2 = 11 hours
