Kima gives her boyfriend 4 kisses every day. To find out how many kisses she gives in a week, we can multiply the daily kisses by the number of days in a week:
\[ 4 \text{ kisses/day} \times 7 \text{ days/week} = 28 \text{ kisses/week} \]
Now, to find out how many kisses she gives in 2 weeks, we multiply the weekly kisses by 2:
\[ 28 \text{ kisses/week} \times 2 \text{ weeks} = 56 \text{ kisses} \]
So, Kima gives her boyfriend 56 kisses in 2 weeks.
