We are given that on Friday she bought two and a half times as much tuna bought on Monday
So, She bought pounds of tuna on Friday =
![2 (1)/(2) * (1)/(4)](https://img.qammunity.org/2021/formulas/mathematics/college/a9dq9196bju0riiy8bi42ic39fmfdtxegn.png)
She bought pounds of tuna on Friday =
![(5)/(2) * (1)/(4)](https://img.qammunity.org/2021/formulas/mathematics/college/fnvlgryfkdr49rlukj05voj3bvz8o37xmr.png)
She bought pounds of tuna on Friday =
![(5)/(8)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ll7m86a1km8vt01i9d6pb4m77bqgnjce02.png)
Hence She bought
