Answer 1

Answer:

x < 12.5 but see below. This is not a straight forward question.

Step-by-step explanation:

Inequality

3.20x < 40

Solution

Divide by 3.2

40 / 3.2 x < 12.5

Here's the question. What do you do with the 0.5? If you think she can buy 1/2 a yard (I think she might be able to in most places stocking bolts of material), then the 0.5 stays.

If you think she can only buy whole yards, then the answer is 12. Since the question does not make it clear, I would go with 12.5 yards. If it marks you wrong then you go with 12.

The question is an inequality. She has to buy less than 12.5
