Question

Vince is saving for a new mobile phone. The least expensive model Vince likes costs $225.90. Vince has saved $122.35.

He used this solution to determine how much more he needs to save.
225.90 ≤ 122.35+ a
225.90- 122.35 ≤ 122.35 - 122.35+ a
103.55 S a
Vince says that based on the solution, he should save a maximum of $103.55.
Is Vince correct?
• Vince is correct because he found the correct solution to the inequality.
• Vince is correct because he should save at least $103.55.
O Vince is not correct because he wrote the wrong inequality to represent the situation.
• Vince is not correct because he should have interpreted the solution as having to save a minimum of $103.55,

Answer 1

No, he is not correct.

$103.55 is the minimum, not maximum, amount that he should save. If he adds the $103.55 to his current total, he can only by the least expensive model. However, he may want to buy more than that model.

Therefore, Vince is not correct because he should have interpreted the solution as having to save a minimum of $103.55.
