Answer:
30 pound.
Explanation:
We have been given that Sals pizza uses 720 pounds of flour in 4 weeks. Sals is open 6 days a week and uses the same amount of flour each day.
First of all, we will find the number of days Sals makes pizza by multiplying 4 by 6 that is
days.
To find the amount of flour used per day, we will divide total flour used by total days as:
![\text{Amount of flour used per day}=(720)/(24)](https://img.qammunity.org/2021/formulas/mathematics/high-school/30sko29nti8yjoxaw5jf2i9duqtfsw3fgy.png)
![\text{Amount of flour used per day}=30](https://img.qammunity.org/2021/formulas/mathematics/high-school/wgwxlg7kyj0llb80w1pzoiyj8mk1t476h1.png)
Therefore, Sal's pizza uses 30 pound flour in 1 day.
