3. a sales manager buys antacid in bottles by the gross. if he goes through 3 bottles of antacid every day, how long will the gross last? (a) 144 days (b) 3 days (c) 20 days (d) 48 days

Answer

Explanation:

Step1: Know the number in a gross

A gross is 144 items. So, the number of antacid bottles is 144.

Step2: Calculate the number of days

We divide the total number of bottles (144) by the number of bottles used per day (3). The formula is $\frac{144}{3}$. $144\div3 = 48$

Answer:

D. 48 days
