Let's assume Taliba can buy n phone cases.
The cost of each phone case is $4.
Therefore, the total cost of buying n phone cases is 4n.
There is also a shipping charge of $7.
So, the total cost of buying n phone cases with shipping is 4n + 7.
Taliba has $31 to spend.
Therefore, we can set up the equation: 4n + 7 = 31.
Solving this equation, we subtract 7 from both sides: 4n = 24.
Dividing both sides by 4, we get: n = 6.
So, Taliba can buy 6 phone cases.
Taliba has $
31
to spend ordering some new phone cases.
Each phone case costs $
4
, and there is also a $
