Question

Abbey has $25. She plans on saving $10 a week. Which inequality shows how many weeks, w, she must save to have at least $250?.

Answer 1

10w + 25 ≥ 250

Explanation:

Abbey wants at least $250. She has a set amount of $25 (constant), and saves $10 each week.

Let "w" be the amount of weeks she needs. Set the equation:

(Amount per week x week) + amount she has ≥ Amount she wants to save.

10w + 25 ≥ 250

Note the wording "at least" (bolded), meaning that she wants $250 or more. Therefore, the sign will be equal to or greater than $250.
