Question

What isRicky needs $45 to buy a jacket. He has saved $15 and plans to work as a babysitter to earn $5 per hour. Which inequality shows the minimum number of hours, n, that Ricky should work as a babysitter to earn enough to buy the jacket? (5 points)

5n ≥ 45 + 15, so n ≥ 12

5n ≤ 45 + 15, so n ≤ 12

15 + 5n ≥ 45, so n ≥ 6

15 + 5n ≤ 45, so n ≤ 6

some one answer me ASAP

Answer 1

Answer: The inequality that shows the minimum number of hours, n, that Ricky should work as a babysitter to earn enough to buy the jacket is 15 + 5n ≥ 45, so n ≥ 6.

This inequality states that Ricky's current savings of $15 plus the amount he earns from babysitting (5n) must be greater than or equal to the cost of the jacket, which is $45. To find the minimum number of hours he needs to work, we set the left side of the inequality equal to $45 and solve for n. 15 + 5n = 45, so n = 6.
