so 3.58 and a 20.00 dollar bill we subtract
20.00-3.58
break it up
20=4+16
16+4-3.58
focus on the 4.00-3.58 part
4.00=3.00+1.00
3.58=3.00+0.58
1.00+3.00-3.00-0.58
1.00-0.58=1.00-(0.60-0.02)=1.00-0.60+0.02=0.40+0.02=0.42

$16.42 is the change

So,

All we have to do is subtract $3.58 from $20 to find the change Jenna received.

20 - 3.58 = 16.42

Jenna received $16.42.
