The inequality and equation is shown below:
4x + 53 ≥ 69
Subtract 53 from both sides:
4x ≥ 69 - 53
4x ≥ 16
Divide both sides by 4:
x ≥ 16/4
x ≥ 4
Therefore, Helena needs to babysit at least 4 kids in order to make at least $69.
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%0D%0A4%0D%0A%0D%0A+%0D%0A53%0D%0A≥%0D%0A69%0D%0A , where x%0D%0A%0D%0A equals the number of kids, to help figure this out. Solve her inequality. Use the letter x%0D%0A%0D%0A as your variable and write your x%0D%0A%0D%0A term first.
