Priya collected 2,400 grams of pennies in a fundraiser. each penny has a mass of 2.5 grams. how much money did priya raise?

Priya raised $9.6

Explanation:

First, we start by getting the number of pennies

To do this, we will simply use cross multiplication

1 penny ....................> 2.5 grams

x pennies ................> 2400 grams

This means that:

Priya raised a total of 960 pennies

Then we get the amount of money she raised:

We know that:

1 penny = $0.01

Therefore:

960 pennies = 960 * 0.01 = $9.6

Hope this helps :)
