Tommy made a mistake in the concept of adding these fractions. He added the numerators together, resulting in 7. He then added the denominators, resulting in 15. His result is 7/15, which is wrong.

What you are supposed to do is find the least common denominator (LCD) of the two fractions. Of 3/10 and 4/5, the LCD is 10. 3/10 + 8/10 (8/10 is the same as 4/5) = 11/10 or 1 1/10

Answer:

0.5 week

Step-by-step explanation:

The time spent by a pound of meat in this system is given by the average number of pounds of meat on inventory (2500 pounds) divided by the average weekly meat consumption (5000 pounds per week).

The time, in weeks, is:

$t=\frac{2500\ pounds}{5000\ pounds/week} \\t= 0.5\ week$

The average time spent by a pound of meat in production is 0.5 week.
