Hello There @Nooraraheem99ox7xzz,
How are you doing?
In this case, Jake has a total of 1 pound of cheese (Before using it)
He uses 6 ounces on the pizza. Lets remind ourselves that:
1 US Pound = 16 Ounces
So, if he uses 6 ounces, then he has 10 ounces left!
Jake has 10 ounces of cheese left after using 6 on the pizza.
I hope I helped, and contact me for further Assistance!
Thank you,
Darian D.
