Helena will receive $53 plus $4 per kid for babysitting this afternoon. She is hoping to make at least $69. How many kids does she need to babysit? She writes the inequality 4x +53 ≥ 69, where x equals the number of kids, to help figure this out. Solve her inequality. Use the letter x as your variable and write your x term first.

Answer 1

To solve the inequality 4x + 53 ≥ 69, we first subtract 53 from both sides:
4x + 53 - 53 ≥ 69 - 53
4x ≥ 16
Then, we divide both sides by 4 to isolate x:
4x/4 ≥ 16/4
x ≥ 4
Therefore, Helena needs to babysit at least 4 kids.
