Apitcher contains 11.25 cups of iced tea. you drink 1.5 cups of the tea each morning and 0.42 cup of the tea each evening. when will you ran out of iced tea?

6th day

Step-by-step explanation:

Start with 11.25 cup.

Each morning and evening, you drink 1.5 cups + 0.42 cups = 1.92 cups

Divide 11.25 cups by 1.92 cups.

11.25/1.92 = 5.86 days

In 5 days (1 morning and 1 evening per day), you will have drunk 5 * 1.92 cups = 9.6 cups.

After 5 days, you have 11.25 cups - 9.6 cups = 1.65 cups

On day 6, you drink 1.5 cups in the morning, now you have 1.65 cups - 1.5 cups = 0.15 cups. You don't have enough for the evening amount of 0.42 cups since you only have 0.15 cups left.

After the morning of day 6, you only have 0.15 cups left. You drink 0.15 cups on the evening of day 6, and you run out.

On the sixth day of drinking.
