Answer to Problem 49PFA

Option B- S takes n bottles of water out of a case of 24 bottles.

Option C- E has n fewer games than J, who has 24 games.

Option E- K is n years younger than her cousin E, who is 24 years old.

Explanation of Solution

Given information : 

The expression as $24-n$ .

 

A. G pays 24 dollars plus n dollars in tax for a shirt.

The expression deduced from the above given situation is $24\text{ dollars }+n\text{ dollars}$ = $24+n$

Thus, this is not the right answer.

B- S takes n bottles of water out of a case of 24 bottles.

The expression deduced from the above given situation is: $24\text{ bottles}-n\text{ bottles}$ = $24-n$

Thus, this is the right answer that matches the situation.

C- E has n fewer games than J, who has 24 games.

The expression deduced from the above given situation is: $24\text{ games}-n\text{ games}$

= $24-n$

Thus, this is also the right answer that matches the situation.

D. M bought n concert tickets for 24 dollars each.

The expression deduced from the above given situation is: $24\text{ dollars }\times n$

= $24\times n$

Thus, this is not the right answer that matches the situation.

E- K is n years younger than her cousin E, who is 24 years old.

The expression deduced from the above given situation is: $24\text{ years - }n\text{ years}$

= $24-n$

Thus, this is also the right answer that matches the situation.

Therefore, Option B,C and E is considered as the right option that perfectly matches the situation.
