To determine how many sundaes can the shop make using all fruits you have to add them together first:
5 3/4 pounds of blueberries
4 1/2 pounds of cherries
Add them to determine the mix
![5(3)/(4)+4(1)/(2)](https://img.qammunity.org/2023/formulas/mathematics/college/we5h6smnvd7dirxfz0np30sso8b7fe3d4y.png)
Then, we know that the show uses 1/6 pound of the mix for each sundae, so yo see how many sundaes you can make, you have to divide the mix by 1/6
![(5(3)/(4)+4(1)/(2))/(1)/(6)](https://img.qammunity.org/2023/formulas/mathematics/college/t0sl6ok2unv2hkw1e8xc9ddtkkhzlapal7.png)
The correct option is the last one.
