Answer 1

Find the difference between the price of each hat and the cost to make it to find the profit per hat:

`12.50-4.90=7.60`

Now, let h be the number of hats sold by Carla, we have that:

`7.60h=1216`

Solve for h:

`\begin{gathered} h=(1216)/(7.60) \\ h=160 \end{gathered}`

She needs to sell 160 hats.
