To determine how many kids Helena needs to babysit, let's start by correcting her inequality. The inequality she wrote is a little off. It should be:
\[ 4x + 53 \geq 69 \]
where \( x \) is the number of kids she babysits.
Next, we can solve for \( x \):
1. Subtract 53 from both sides:
\[
4x \geq 69 - 53
\]
\[
4x \geq 16
\]
2. Divide both sides by 4:
\[
x \geq 4
\]
So, Helena needs to babysit at least **4 kids** to make at least $69.
\[ 4x + 53 \geq 69 \]
where \( x \) is the number of kids she babysits.
Next, we can solve for \( x \):
1. Subtract 53 from both sides:
\[
4x \geq 69 - 53
\]
\[
4x \geq 16
\]
2. Divide both sides by 4:
\[
x \geq 4
\]
So, Helena needs to babysit at least **4 kids** to make at least $69.
