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

The inequality is 4x + 53 ≥ 69.

To solve the inequality, we start by subtracting 53 from both sides:

4x + 53 - 53 ≥ 69 - 53

This simplifies to:

4x ≥ 16

Next, we divide both sides of the inequality by 4:

4x/4 ≥ 16/4

This simplifies to:

x ≥ 4

Therefore, she needs to babysit at least 4 kids.
