(MP) Use Tools A bobsled team is practicing runs on a track. Their first run takes 4.85 minutes. On each of the next two runs, the team's time changes by \( -5 \frac{1}{2} \% \) compared to the previous time. A. What was the team's time, rounded to the nearest hundredth of a minute on their final run?

\( \lim _ { x \rightarrow 0 ^ { + } } \frac { \sqrt[ 3 ] { x \sin ^ { 2 } ( 2 x ) } ( \sqrt { x } - 1 ) } { e ^ { x } - \cos ( 3 x ) } \)

Mrs Brown gave \( \frac{4}{7} \) of her money to her son. He spent \( \frac{2}{5} \) of the money on a pair of shoes and the rest on two books that cost \( \$ 18 \) each. How much did Mrs Brown have at first?
