Answer 1

                                      Answer and Explanation

__________________________________________________________

A. Step 2

B. Step 2 is wrong because multiplying is first before adding, and Laura added before multiplying and got 401.5 instead of 338.5

C. $5\cdot\left(\left(3.14+4.16\right)\cdot9+2\right)$ = $?$

     $5\cdot\left(\left(7.3\right)\cdot9+2\right)$ = $?$

     $5\cdot\left(65.7+2\right)$ = $?$

     $5\cdot\left(67.7\right)$ = $?$

D.  $338.5$
