To represent Grace's earnings from babysitting as an inequality, we can start by noting her earnings formula:
Grace's total earnings = $50 + $5 per child, which can be expressed as: \[ 50 + 5x \]
where \( x \) is the number of children she babysits. Grace wants to make at least $63, which translates to the inequality: \[ 50 + 5x ≥ 63 \]
This is the inequality that can be used to solve the problem.
