To determine how many kids Helena needs to babysit to make at least $69, we start with her inequality:
\[ 4x + 53 > 69 \]
where \( x \) represents the number of kids she babysits.
Let's solve the inequality.
1. Subtract 53 from both sides:
\[
4x > 69 - 53
\]
\[
4x > 16
\]
2. Now, divide both sides by 4:
\[
x > \frac{16}{4}
\]
\[
x > 4
\]
Helena needs to babysit more than 4 kids to make more than $69. Since she can't babysit a fraction of a kid, she must babysit at least 5 kids.
So, the number of kids Helena needs to babysit is **at least 5**.
\[ 4x + 53 > 69 \]
where \( x \) represents the number of kids she babysits.
