Answer:

$B = \frac{3}{2} * 21,356$

Step-by-step explanation:

Given

Represent Jimmy with J and Bob with B

$J = 21,356$

$B = 1\frac{1}{2} * J$

Required

Determine the expression for B

$B = 1\frac{1}{2} * J$

Substitute 21,356 for J

$B = 1\frac{1}{2} * 21,356$

Convert Mixed fraction to improper

$B = \frac{3}{2} * 21,356$

The above is an expression for B

Solving further, we have

$B = \frac{3 * 21,356}{2}$

$B = \frac{64068}{2}$

$B = 32034$
