The amount that Susan charges per hour for babysitting is directly proportional to the number of children she is watching. She charges $4.50 for 3 kids.

Question

How much would she charge to babysit 5 kids?

$7.50
$6.50
$1.50
$3.33

Answer 1

Since Susan's charges are directly proportional to the number of children she is watching, we can set up a ratio to find her rate per child.

Given that Susan charges $4.50 for 3 kids, we can find her charge per child:

\[ \text{Charge per child} = \frac{$4.50}{3} = $1.50 \]

Now, to find out how much she would charge for 5 kids, we multiply the charge per child by the number of kids:

\[ \text{Charge for 5 kids} = 5 \times $1.50 = $7.50 \]

So, Susan would charge $7.50 to babysit 5 kids.
