Rebecca drinks at least 7 cups of water each day. So far,she drank 1.5 cups. She will drink the rest of her water from a bottle that holds 1.5 cups. Write an inequality for the minimum number of bottles of water she will drink.

Let x represent the minimum number of bottles of water Rebecca will drink.

Since each bottle holds 1.5 cups of water, the total amount of water she will drink from the bottles is 1.5x cups.

Rebecca has already drunk 1.5 cups, so the total amount of water she needs to drink is 7 cups.

Therefore, the inequality for the minimum number of bottles of water she will drink is:

1.5x ≥ 7 - 1.5

Simplifying:

1.5x ≥ 5.5

To find the minimum number of bottles of water Rebecca will drink, we need to consider that she has already consumed 1.5 cups of water and needs to drink the rest from a bottle. Let's assign a variable to represent the number of bottles she will drink.

Let's say the number of bottles Rebecca will drink is 'x'. Since each bottle holds 1.5 cups of water, the total amount of water she will consume from the bottles will be 1.5x cups.

We know that Rebecca drinks at least 7 cups of water each day. Therefore, the total amount of water she consumes in a day is the sum of the water she has already drunk and the water she will drink from the bottles. This can be represented by the inequality:

1.5 + 1.5x ≥ 7

In this inequality, 1.5 represents the cups already consumed, 1.5x represents the water she will consume from the bottles, and 7 represents the minimum daily consumption.

Simplifying the inequality, we have:

1.5x ≥ 7 - 1.5

1.5x ≥ 5.5

Dividing both sides of the inequality by 1.5, we get:

x ≥ 5.5/1.5

x ≥ 3.67

The minimum number of bottles of water Rebecca will drink is 4, since she cannot drink a fraction of a bottle.
