Question

Albert wants to save money for his party. He needs at least $420 in 9 weeks and already has $60. Which inequality represents how much money Albert should save every week (x)?

a) x ≥ 50
b) x ≤ 50
c) x ≥ 40
d) x ≤ 40

Answer 1

c) x ≥ 40

Step-by-step explanation:

Albert's $60 can be subtracted from his goal of $420 to give the amount he needs to save to reach his goal of at least $420 (≥ $420).

Albert needs ≥ $360

He needs to save it over 9 weeks, so we can say that x, the amount he needs to save each week, is (≥ $360)/9 weeks.

x ≥ $40

c) x ≥ 40

Answer 2

Albert should save at least $40 every week.

Step-by-step explanation:

To find the amount of money Albert should save every week, we can subtract the amount he already has from the amount he needs and then divide by the number of weeks. So the inequality is:

x ≥ (420 - 60) / 9

Simplifying this inequality, we get:

x ≥ 360 / 9

x ≥ 40

Therefore, the correct inequality is x ≥ 40, which means that Albert should save at least $40 every week.
