Answer:
Explanation:
Let x be the number of children Grace babysits. Then, she will earn $50 + $5 per child, or a total of $50 + 5x. To make at least $63, we can write an inequality as follows:
50 + 5x >= 63
To solve for x, we can subtract 50 from both sides:
5x >= 13
And finally, divide both sides by 5:
x >= 2.6
Since Grace needs to babysit at least 2 whole children, she needs to babysit at least 3 children to make $63 or more.
