• Christina estimates that she will spend $250.
• She actually spent $350.

The percentage error refers to the percentage that represents the difference, so, first we can divide 250 by 350, that will give us the percentage that represents 250.

`(250)/(350)= 0.71`

Then, we multiply by 100

`0.71 * 100= 71\%`

Now, we subtract

`100\% - 71\%=29\%`

Therefore, the percentage error is 29%, that is, she missed her estimation by a 29%.
