Final answer:
To hire a babysitter for 6 hours, it would cost $72.
Step-by-step explanation:
To find out how much it would cost to hire a babysitter for 6 hours, we can use the given information that the cost is proportional to the number of hours hired. We can set up a proportion to solve for the unknown cost:
$48 / 4 hours = cost / 6 hours
Cross multiplying, we get: 4 * cost = 6 * $48
Simplifying, we have: cost = (6 * $48) / 4
Therefore, the cost to hire a babysitter for 6 hours would be $72.
