Elena earns $6 an hour babysitting for 2 children. a. She charges $8 for 3 children. a) Is her rate proportional to the number of children? b) .If she uses a proportional rate, how much should she charge for 5 children? c).Explain how you arrived at your answer in part b.

See below.

Step-by-step explanation:

a)

2 children

$6/hour / 2 children = $3/hour per child

3 children

$8/hour / 3 children = $2 2/3 /hour per child

Her rate is not proportional to the number of children since it is $3/child for 2 children and $2 2/3 / child for 3 children.

b)

Since for 2 children she charges $3/hour per child, for 5 children multiply the rate by 5.

5 * 3 = 15

The proportional rate for 5 children is $15/hour

c)

I use the hourly rate for 1 child I calculated in part a) and multiplied by 5 to account for the 5 children.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
