Write the solution to the given inequality in interval notation.

Choice C)

Explanation:

There are two parts to this graph. The left part is the portion from negative infinity up to 4. Both endpoints are excluded. We always exclude infinity as you can never reach it. We exclude 4 due to the open hole at this location. This is the compound inequality which is in interval notation. The curved parenthesis tell the reader to exclude the endpoint.

For the right portion of the graph, we start at 5 and end at positive infinity. We exclude the endpoint 5 as well because there's an open hole here too. So we say this is and that turns into the interval notation

The last step is to glue the two intervals together through the use of a union symbol. So and combine to get

Nowhere in the answer is a square bracket because we do not include either endpoint.

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
