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.

1 answer

The inequality is 4x + 53 ≥ 69.

Subtract 53 from both sides:

4x ≥ 16

Divide by 4:

x ≥ 4

Helena needs to babysit at least 4 kids in order to make at least $69.
