Ответ:
The inequality equation is
(2,764 + x) ≥ 5,000
Solving further, we obtain
x ≥ 2,236
where x is the amount of money the Li's family still need to save.
Step-by-step explanation:
Li’s family is saving money for their summer vacation. Their vacation savings account currently has a balance of $2,764. The family would like to have at least $5,000.
Which inequality can be used to determine the amount of money the family still needs to save?
Solution
Let x represent the amount of money the Li's family still need to save.
It is given that the family already have $2,764 in their savings account and the family needs at least $5,000.
The total amount the family will have in total, after saving x dollars to join the already saved $2,764 will now be
$(2,764 + x)
This amount must be at least $5,000, that is, this amount must be greater than or equal to $5,000.
So, the inequality equation is then
(2,764 + x) ≥ 5,000
Solving further by subtracting 2,764 from both sides, we obtain
x ≥ 2,236
Hope this Helps!!!
