Question

The sum of 4.5 and one-third a number is equal to at most 38.9. What are all the possible values of the number? How would you write an inequality that could be used to solve this problem?

a. 4.5 + ‡ + n 5 38.9, where n is equal to the number.

b. =n +4.5 ≥ 38.9, where n is equal to the number.

c. In +4.5 = 38.9, where n is equal to the number.

d. In + 4.5 < 38.9, where n is equal to the number.

The correct inequality that could be used to solve this problem is:

d. n/3 + 4.5 ≤ 38.9, where n is equal to the number.

To solve this inequality, we can subtract 4.5 from both sides:
n/3 ≤ 34.4

Then, we can multiply both sides by 3 to isolate the variable:
n ≤ 103.2

Therefore, all the possible values of the number (n) are any number less than or equal to 103.2.
