5.Helena will receive $53 plus $4 per kid for babysitting this afternoon. She is hoping to make at least $68. How many kids does she need to babysit? She writes the inequality 4x+53≥68, 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 that represents the situation is 4x + 53 ≥ 68, where x represents the number of kids.

To solve this inequality, we need to isolate the variable x.

First, subtract 53 from both sides of the inequality:
4x + 53 - 53 ≥ 68 - 53
4x ≥ 15

Next, divide both sides of the inequality by 4:
4x/4 ≥ 15/4
x ≥ 3.75

Since we are talking about the number of kids, the number of kids cannot be a decimal. Therefore, Helena needs to babysit at least 4 kids in order to make at least $68.
