Question

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? Write an inequality that could be used to solve this problem. Use the letter x as the variable, and write the inequality so that the x term comes first.

Answer 1

Explanation:

Well if you do this
`$50 + $5=x\\50+5= 55+50+5=110`you will only have to babysit 2 kids and you will have leftover money.

`65-110=x 65-110=153`

Answer 2

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.
