1. a coffee shop uses 4 liters of milk every day. a. if there are 15 liters of milk in the refrigerator, after how many days will more milk need to be purchased? explain how you know.

Explanation:

Step1: Divide total milk by daily use

$\frac{15}{4} = 3.75$

Step2: Interpret the result

Since the shop uses milk each full day, after 3 full days, $3 \times 4 = 12$ liters are used, leaving $15 - 12 = 3$ liters, which is not enough for the 4th day. So more milk is needed after 3 days.

Answer:

More milk will need to be purchased after 3 days. After 3 days, 12 liters of milk will have been used, leaving only 3 liters, which is not enough to cover the 4 liters needed for the 4th day.
