Answer :
[tex]multiply\ percent\ by\ cost\ of\ soda\\\\
20\%*12=0.2*12=2.4\$\\\\
sale\ price=12\$-2.4=9.6\$\\\\Sale\ price\ is\ equal\ to\ 9.6\$.[/tex]
20/100 times 12 = 2.40
then, 12 minus 2.40 = 9.60
~~~~~~~~~~~~~~~or~~~~~~~~~~~~~
80/100 times 12 = 9.60
then, 12 minus 2.40 = 9.60
~~~~~~~~~~~~~~~or~~~~~~~~~~~~~
80/100 times 12 = 9.60
