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

To solve the inequality 4x + 53 > 69, we need to isolate the variable x.

First, subtract 53 from both sides:
4x + 53 - 53 > 69 - 53
4x > 16

Next, divide both sides by 4:
(4x)/4 > 16/4
x > 4

So, she needs to babysit more than 4 kids in order to make at least $69.
