d. all three offer the same price.

B. Consultant B

Step-by-step explanation:

The question asked us to determine the price each consultant charges for a period of 5 hours and then get the cheapest among them.

Let the total charges for 5 hours session = a

Consultant A

He charges $160 for the first hour and $75 after the first. That means the remaining 4 hours he charges 75 ×  4 = $300.

a = 160 + 300 = $460

Consultant B

He charges $90 per hour. This means his charge for 5 hours session is 5 × 90 = $450

a = 90 × 5 = $450

Consultant C

He charges $140 for the first hour and $80 after the first hour. The remaining 4 hours session he will charge 4 × 80 = $320.

a = 140 + 320 = $460

Consultant B offers the cheapest price of $450

I am not sure which symbol you meant to include so will do all four of them:

y > -5   >     (-5, ∞)

y ≥ -5   >     [-5, ∞)

y < -5   >     (-∞, -5)

y ≤ -5   >     (-∞, -5]

The PARENTHESIS is used when the number is NOT included (open dot).

The BRACKET is used when the number IS included (closed dot).
