We have been given that the biggest bowl of mashed potatoes ever made weighed [tex]4.5\times 10^4[/tex] pounds and was created at the Iowo State Fair in 2005. The biggest deep dish pizza ever made was in Chicago in 1998. It weighed a whopping [tex]1.23\times 10^5[/tex] pounds.
To find how much pizza weighs more than bowl of mashed potatoes, we will subtract weight of mashed potatoes from weight of pizza.
[tex]1.23\times 10^5-4.56\times 10^4[/tex]
[tex]1.23\times 100000-4.56\times 10000[/tex]
[tex]123000-45600=77400[/tex]
Now we will convert [tex]77400[/tex] into scientific notation as:
[tex]77400=7.74\times 10^4[/tex]
Therefore, the pizza weighs [tex]77400=7.74\times 10^4[/tex] pounds more than the bowl of mashed potatoes.
