Question

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

Start with Helena's inequality:
4x + 53 ≥ 69

Subtract 53 from both sides:
4x ≥ 16

Divide both sides by 4:
x ≥ 4

So Helena needs to babysit at least 4 kids (x ≥ 4).
