Final answer:

The price of a 16-minute phone call is $2.40.

Step-by-step explanation:

To find the price of a 16-minute phone call, we can set up a proportion using the given information. Since the price of a 9-minute phone call is $1.35, we can say:

$1.35 / 9 minutes = x / 16 minutes

To solve for x, we can cross multiply:

$1.35 * 16 = 9x

Dividing both sides by 9, we get:

x = $1.35 * 16 / 9 = $2.40

Therefore, the price of a 16-minute phone call is $2.40.
