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 know the answer is 3
