To estimate the amount of money in the jar at the end of the first month using the line of best fit, we can substitute \( m = 1 \) into the given equation \( B = 0.45m + 1.93 \).
Substituting \( m = 1 \):
\[
B = 0.45(1) + 1.93
\]
\[
B = 0.45 + 1.93
\]
\[
B = 2.38
\]
Thus, the best estimate of the amount of money in the jar at the end of the first month is **$2.38**.
