A 7-pack of light bulbs costs $2.45. What is the unit price?

per bulb

0.35 per light bulb

Step-by-step explanation:

In order to find the unit price per bulb, we must set up a unit rate.

To do this, divide the cost for the pack by the number of light bulbs in the pack.

cost/bulbs

We know that a 7 pack of bulbs costs $2.45.

cost = $2.45

bulbs = 7 bulbs

$2.45/7 bulbs

Divide 2.45 by 7 (2.45/7=0.35)

$0.35 / bulb

The unit price per bulb is 0.35.
