To write the inequality, we can express Grace's total earnings in terms of the number of children she babysits, represented by the variable \( x \).
Grace's total earnings can be expressed as:
\[ 50 + 5x \]
She wants to make at least $63, so we can set up the inequality:
\[ 50 + 5x \geq 63 \]
This inequality represents the condition that Grace's earnings must be greater than or equal to $63.
