grace will receive 50 plus 5 per child for babysitting this afternoon she is hoping to make at least 63 to buy a new video game tonight how many children does she need to babysit
Let the number of children she needs to babysit be x.
The total amount Grace will receive for babysitting x children is 50 + 5x.
According to the question, she needs to make at least 63.
So, 50 + 5x ≥ 63.
Subtracting 50 from both sides, we get:
5x ≥ 63 - 50
5x ≥ 13
Dividing both sides by 5, we get:
x ≥ 13/5
x ≥ 2.6
Since she cannot babysit a fraction of a child, she needs to babysit at least 3 children to make at least 63.
