Question

An electrician is hired to install a ceiling fan. She estimates that the installation will take no more than 45 minutes if the house is up to building code. If the house is not up to building code, she estimates that the installation will take longer than 120 minutes. Which graph represents the number of minutes it could take her to install the fan?

Answer 1

She estimates that the installation will take no more than 45 minutes if the house is up to building code.this means that the arrow is at 45 with a hollow circle pointing to the left because > 45
If the house is not up to building code, she estimates that the installation will take longer than 120 minutes. this means that the arrow is at 120 with a hollow circle pointing to the right because < 120so the answer is the 3rd picture

Answer 2

Answer : option C

An electrician is hired to install a ceiling fan. She estimates that the installation will take no more than 45 minutes if the house is up to building code. The installation will take 45 minutes or less than 45 minutes. So we put a solid circle at 45 and shade to the left.

If the house is not up to building code, she estimates that the installation will take longer than 120 minutes. The installation will take more than 120 minutes. So we put a hollow circle at 120 and shade to the right.

So third diagram is correct.
