Answer:
B. [144, 174]
Step-by-step explanation:
Given
Total Weight Range = Not less than 145lb and Not more than 175lb
Required
Determine the actual weight range
Let x represent the total possible weight of a bodybuilder
From the question, we understand that the total weight is within the range of 145 to 175. i.e. [tex]145\leq x\leq 175[/tex]
Also from the question, we understand that the bodybuilder's cloth adds 1 lb to the total weight;
The next step is to subtract this 1 lb from the range of total weight to get the actual weight range
This is as follows
[tex]145 - 1 \leq x \leq 175 - 1[/tex]
This gives
[tex]144 \leq x \leq 174[/tex]
From the list of given options, the correct answer is [144,174]
