Option C : f+23 is the correct answer.

Step-by-step explanation:

Given that:

Amount Dominic wants everyone to contribute = $2

Number of relatives who have contributed = 23

The expression is;

2(f+23)

As we know that 2 represents the amount and 23 represents the number of relatives who have donated, therefore,

f represents the number of people who would donate to the library fund, and

f+23 represents the total number of people who contributes to the fund.

Hence,

Option C : f+23 is the correct answer.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
