To calculate Emmet's score at the end of Level 1, we start with the points he earned and then subtract the points he lost.
Emmet earned 14 points for finding the foot bone. Then, he lost 17 points for breaking it.
We can express this as:
\[ \text{Score} = \text{Points Earned} - \text{Points Lost} \]
Substituting in the values:
\[ \text{Score} = 14 - 17 \]
Calculating this gives:
\[ \text{Score} = -3 \]
Therefore, Emmet's score at the end of Level 1 is \(-3\) points.
