See the solution process below:

First, let's call the score she needs in the third game #s#.

The total score or the sum of the three games must be at least 627 and we know the score of the first two games so we can write:

#222 + 194 + s >= 627#

Solving for #s# gives:

#416 + s >= 627#

#-color(red)(416) + 416 + s >= -color(red)(416) + 627#

#0 + s >= 211#

#s >= 211#

For Karina to have a total score of at least 627 the third game must be a 211 or higher.
