Final answer:
It will take about 7 days to use the inventory of shipping labels.
Step-by-step explanation:
To find how many days it will take to use the inventory of shipping labels, we need to divide the total number of shipping labels by the number of shipping labels used per day.
The total number of shipping labels is 500 and the worker ships 25 boxes each day, with each box containing 3 shipping labels.
So, the worker uses 25 x 3 = 75 shipping labels per day.
Dividing the total number of shipping labels (500) by the number of shipping labels used per day (75), we get 500 / 75 = 6.67.
Rounding to the nearest whole number, it will take about 7 days to use the inventory of shipping labels.
