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.

To solve the inequality \( 4x + 53 \geq 69 \), follow these steps:
Subtract 53 from both sides: \[ 4x + 53 - 53 \geq 69 - 53 \] \[ 4x \geq 16 \]
Divide both sides by 4: \[ \frac{4x}{4} \geq \frac{16}{4} \] \[ x \geq 4 \]
So, Helena needs to babysit at least 4 kids to make at least $69.
The answer in inequality form is: \[ x \geq 4 \]
