Question

You begin the week with 20 units of milk. You purchase 40 units. Your ending inventory for the week is 30 units. How many units did you sell?

Answer 1

Answer:

30 units.  

Step-by-step explanation:

Let x be number of milk units sold.

It has been given that You begin the week with 20 units of milk. You purchase 40 units. Therefore, total units of milk will be $20+40=60$ units.

It has been given that your ending inventory for the week is 30 units, which means after selling x units from 60 units you are left with 30 units.

We can set this information in an equation as:

$60-x=30$

$-x=30-60$

$-x=-30$

$x=30$

Therefore, you have sold 30 units.
